BRB
Focus on combined arms and reduced efficiency of deathstars, magic and cannons.
I agree with this in principle but not in implementation.
Maximum amount of point per unit are 450pts not including characters. There can only ever be two characters in one unit (most deathstars just died).
I have been tabled by enough MSU armies that I don't believe Deathstars are a problem. Very specific Deathstars are the problem. Such as Banner of the World Dragon. I think 450 points is a too tight of a limit. I think max of two characters is too tight of a limit. I am dubious if Deathstars need any formal limits at all, but if they do, I would suggest this for a lighter restriction. "At least three models of the rank and file models need to be in the front ranks at all times." This will blunt the worst excesses of Deathstar use without forcing everyone to play MSU.
Magic resistance work on all magical damage from spells, however their price is now: 20/40/60 and do not stack with a ward save.
I can vaguely understand that MR price would go up if MR became better. Note that is more complicated than changing the price of the BRB items with MR. There are lots of army book units with built in MR, they would all need some kind of price adjustment. I am neither supportive or opposed to not letting it stack with ward saves. First I want to know the rationale behind this.
Also, note that you would need to address more than Dwellers and Purple Sun. While they are the two worst culprits for OP spells, you would need to give all the army book lores a hard look and nerf almost every nuke spell. But I would think with the expanded magic resistance, the nuke spells do not need to addressed directly. A small implementation of magic resistance rules being changed would be a lot less trouble than adjusting every spell.
Magic miscast table to be changed so spending a low amount of dice doesn't result in dimensional cascade.
@hdctambien mentioned (modified by me) the following:
Roll 1d6 + X where X is the number of dice you used to cast the spell:
2 wizard can't cast any more.
3-4 casting wizard takes s6 hit.
5 -6 s6 small template. d6 dice are lost.
7-8 all wizards take S6 hit. d6 dice are lost.
9 - 10 Wizard loses d3 levels and can't cast any more.
11-12 Dimension cascade.
Note if you six dice something, you know have a 1 on in 3 chance of dimensional cascading. That's huge. Especially since one of the biggest complaints about 8th edition was that magic casting had a "Hail Mary" go for broke feel. This exacerbates it. I'm not sure many people will like it.
Also, the Soul of Stone and everything that adjusts miscasts would need a rewrite. Also, this biases the whole system towards spamming cheap spells which means Lore Mastery should go up in points across all armies. Things like Wandering Deliberations should go up in points across all armies, things that allow additional spells should go up in points across all armies. That's a lot of minor changes to debate over from one change.
The system also weakens L1 and L2 caster because they might be stuck with high value casting spells. It might be easier to rewrite all the lore description, make most spells light and easy to cast but give more spells high casting value variants (think Fireball on a grand scale)
It might be better to change all spell lists. That level of change is more for a true 9th edition as opposed to a patch job on 8th which is what I think we are going for.
Change cannons to do D3 +1 wounds. Lone character can very easily die, but monsters will on average take 3 wounds and cannot be one-shotted. Shooting a character on monster is randomized (1-4 = monster, 5-6 = character).
This is too extreme. Looks fine here because we are on the cannon magnet side, but players with cannon using armies will not accept this. If 1d3+1 cannons goes through they will negotiate for cheaper cannons. Then cannons will STILL be broken because of cannon spam. Better to make adjust the points of cannons and leave it at that.
The BSB reroll can only ever be taken in the unit the BSB is positioned in.
Fear grants a -1Ld modifier to the enemy. Should the test fail WS is reduced to WS1.
Terror grants a -2Ld modifier to the enemy and only work in close combat. Should the test fail WS is reduced to WS1 and ASL is gained. Units with ASL reroll successful to hit rolls.
I disagree. This weakens BSBs too much which is a fundamental part of the game. Modifying Fear and Terror to this extant will only require every Fear and Terror causing unit and every immune to psychology unit to have to be reevaluated. This level of change will freak people out and cause them lash out at all our of proposed changes. Also it looks self serving considering our dinosaurs.
Like with cannons it's much easier to just adjust the points cost of Fear and Terror causing creatures. AND it makes selling our concept to other groups easier. "40 points cheaper? How about 30 points cheaper?" You can't negotiate that easily when you are changing core rules.
Lords:
Slightly reduce price of Slann.
Change price on disciplines.
We need to increase the incentive to pick the more obscure dicsiplines.
The disciplines definitely need price modifications but very few non-LM players will stomach Slann becoming cheaper, especially since your proposed magic phase changes would only make them stronger.
Skrox (should be an actual unit entry!):
Agreed.
For every kroxigor you add you also add 10 additional skinks.
Agreed in principle, 10 Skinks to one Kroxigor seems better than 8 to 1 but I'm not sure Kroxigor should come in bundles. I think it'd be more user friendly to decide how many Skinks and then decide how many Kroxigor.
Skinks can be both musician and banner while a kroxigor can be a champion.
-1 To Hit against a the kroxigors.
You can only hit a kroxigor if you're in B2B contact with a skink that's in B2B contact with a kroxigor.
At 450pts you can at most have 4 kroxigors and full command.
I don't have a problem with any of these rules individually, but when put together it gets wonky.
-1 to hit against Kroxigors because icky when a Kroxigor is the unit champion. Especially if challenges are involved.
Combine the 450 limit with -1 to hit Kroxigor and you are spoonfeeding your enemy how to kill Skroxigor. The Skinks are killed in droves, lose Steadfast and break.
I am on the fence about making Swarms core and making Saurus character more expensive, but I agree with the most of the rest of your army list suggestions.
