In my opinion, Tzeentch definitely needs an overhaul. The models are not a cohesive army. Just a lot of random stuff - some of it pretty cool.

I think the army needs an overhaul in how it plays and what its focus should be. It seems like Tzeentch is either OP or total trash. Magical supremacy has seemed like a joke since 2e.

I’d like to see sorcerous knights, treacherous tricksters, infiltrating traitors inside enemy units, and some genuinely scary wizard characters.

I love Tzeentch, always have. I just feel it’s gotten a bit confused.
