My thoughts on some "changes" to improve mark of Tzeentch which is widely considered the weakest mark of chaos at the moment. I think the easiest improvement would be to grant inferno rounds (dps boosting ammo) to weapons, the added damage would make the wearer essentially a glass cannon type build and improve ranged damage at the cost of reduced survivability. For sorcerers I think the Tzeentch spells just need buffed. Flickering fire should be significantly more threatening as the wearer is already one of the squishiest classes in the game, it draws from the same pool as healing, and has to be aimed. Boon of change could be improved in a couple of ways, either by adding some sort of buff/mutation to it (ie damage increase or resistance), or by making it a ranged aoe spell. Not sure how to tag devs, but Mark and spells are way overdue for some love.
