Major Change
This main idea may make the lizard community bash me but I think it will simultaneously solve multiple issues. I would remove the cold blooded rule from all non-character models in our army, and modify the rule so that characters grant it to units they join, and the frog has a special rule that grants it according to his leadership bubble.
This would lower the cost of every unit across the board (9th Age always makes you pay for rules even if not used), it would give an incentive to field on foot characters and more basic non fully tooled out characters, and it would immediately give the frog an extremely solid reason to field him instead of just the magic phase. There are a couple units that I think could use a bump in leadership to offset this though, I think ld6 should be the minimum in our army. On a side note there should be some historic reference to how much 9th Age decided cold blooded rule was worth to each unit and I'm guessing it was pretty pricey.
This would essentially reduce points for:
1) skinks in core bringing them more in line for their stats
2) saurus which would then bring their efficiency up and allow other options
3) raptor riders which are already grossly overcosted
4) temple guard who never ever needed the rule anyways
5) etc
That basically covers the change to the frog for me, I like the idea of fixing his low cost disciplines, removing his inherent 4+ ward save, and allowing a palaquin upgrade with temple guard stats like VS war litter.
Raptor Riders
There have been a few good ideas, like adding wounds, adding initiative to charging lances, etc. For me I think adding in a chasing prey rule, where all casualties are taken out at initiative 0. Everyone I have heard is not saying that they die too easily but that they die before they can hit, this allows the enemy to hit at their full ability as normal, does not increase any survival, but does allow for maximum damage on our part. So that should be a fairly low cost option to add, unlike hitting before others (which then allows for less of our guys dying and possibly upsets other balances). I also think they are extremely overcosted even after adding this rule, elf cold ones have almost the exact same damage output and stats as us (1 less attack but their attack hits a lot more often) and are much much cheaper.
Skinks
I'm not really that concerned about skirmishing and poison, I like the hunters as they are and I would like to see additional hand weapons back. But they are overcosted in combat, they need a significant point decrease if they have no poison shooting option taken. The other option is to buff their stats to minimum close combat, ie WS3, T3 after that they would be viable as they have already been fed close combat synergies.
Saurus
I really like where they have been moving towards, I would like the totems worked a bit more and a slight point decrease, and for saurus characters to be able to buff the unit. But overall a good spot, spears need to be 1 point, yes they are a better offensive weapon, but the benefits to parry are so significant to this unit it really has made no sense to any of my games with them to pay 2pts for spears, even at 1pt I will probably only include spears 1/3 games.
Temple Guard
These guys need some serious help, I would like to see it in the form of options like WotDG chosen have, so let them get GWs (the models would already support the idea) and heavy army. Totems possibly to improve things like predatory fighter, initiative, movement. Their points right now are overcosted, but I could see increasing their overall points with some options selected and it being at a good spot, if saurus have elite stats then elite saurus should be expensive and deadly. Side note, removing cold blooded from them would free up points to make them better fighters.
Born Predator
I like the re-rolling ones, it gives a more consistent output than adding attacks on a 6, but I think I wouldn't mind it changing again either. So if it is going to change this is my idea:
Add paired weapon rule to any model fighting with a shield and devastating/thunderous charge to any model without a shield. It would function a lot like the ogres ironfist rule except it wouldn't give parry rules. When swapped for the current rule I think a point increase would be justified, but it would add initiative and an attack, we would function more like savage orc eadbashers. It would benefit MSU playstyles more but also add key opponent counters.
the idea is that saurus can use anything as a weapon especially their shields and I think it is unique and fills the gap our saurus have been feeling for the last few editions. It would also work with current models, and could instead be a totem but it might be too powerful when combined with the current predatory fighter rule.
Summary
So there you have it, major changes to cold blooded and born predator, I think born predator would inflict a cost increase from the current rule (Still not as good as ogre ironfist, more on par/slightly better than orc +1 S). But removing cold blooded from all units would also bring a fairly massive point decrease, please think about all that we could do with those points and just what units would be effected and how you could work around it before starting the tar and feathers on me
Guess I need to read more thoroughly, though to me the whole new layout of rules is rather muddled, but that's probably just because I was so used to the GW layout. Thanks for the info! I'll go read through it now
