Asamu's rankings are petty good but I would bump DE down a tier (they lost a lot and have some bad matchups) and VC up a tier when played right with the right but I know some tournament players that haven't figured out VC yet. The difference between the tiers in terms of probability and consistsency of winning is a lot less now than it was a few years ago in 8th edition and certainly much much better compared to the state at the end of 7th edition. So much depends on the exact build and play-style and who is playing the army, which is as it should be. I know a guy who loves his TK and wins with ithat army consistently. I know a couple of guys who swear that beastmen played right are much better that O&G. I know someone who won a GT with Woodies. Luck in matchups (pne army and build can be weak to another) and a few misplays seem to determine at lot in actual results. If I run an optimal Nurgle Daemons army wiith skullcannons, I will walk all over some armies but get killed by certain heavy magic armies, especially if they have strong magic, HE with BOTWD on a key unit, or lore of light lore.
Lizardmen have been neutered a bit, but I think they are still very competitive and can win any tournament. Especially if the scenerios and terrain are favorable. Lizardmen have now become that complete Army without listening to that player across the table bitching about my slann being too dirty. I can build a slann that can be just as effective as my 7th edition one. Yeah I don't get the free dice, but with the new lore and skinks holding beasts we become a hard to handle army. In the Northwest tournament seen is the last 4 months. Lizardmen have won a couple of them and are firmly fighting for those spots in second and third. The tier system is skewed any how. You can build a "tougher than nails list" and still lose based on bad roles, or terrible scenario, and or terrain. It's a crap shoot a lot of the time. Bottom line Lizardmen look good and they got some new refreshing things to incorporate into our builds. have fun, and destroy those other races.
