I have a ton of suggestions for Chaos Warriors.
Daemon Prince can choose LA or HA, not chaos armour. Boosted the lore of Tzeentch Strength for spells, replaced warpflame with flaming attacks like 7th ed. Slaughterbrute +1A, no longer have Extra Claws, 220 pts. Chimera moved to Rare, 200 pts, no random attacks. Chaos Spawn moved to special, move 3D6. Skullcrushers moved to special, 68 pts. Chaos Chariot and Gorebeast chariot merged into one Core choice.
Forsaken are Skirmishers have have HA, 15 pts. Marauder Horsemen I3, have shields by default, 13 pts. Marauders I3, 4 pts, cheaper GW's and flails. Chaos Warriors I4, 15 pts (meaning that Elves are still faster, as they should be, and keeps GW's from being too good in 9th ed).
WoC now sports a total of 8 core units, 13 special units and 8 rare units! Likewise, all monsters have moved to rare. I've done quite a lot of reorganizing in the army list, with chariots and Knights all being core units (like 6th ed) and MC has been moved to special (like several other armies have). A bit later than planned, mainly due to the insane number of units WoC have (which is rather ironic considering how few Mortal units they had back in 6th ed!).
