chaplains would be cool for buffing and debuffing with auras apothecaries for healing and buffing via heals and stims, stronger melee, faster move speed, health regen techmarines buff and support via ammunition, armor regen, weapon enhancements Librarians could do AoE warp stuff or single target, but mayybe to balance they have to choose which tree they commit to. They could even have self buffs also end music is pretty loud but if thats the choice ur going for i respect it lol
I'm really hoping they do a horde mode that's more based off of gears of war, which would allow us to place stuff during our defense. I was hoping to see some necrons since we appear to be on a tombworld at the end of the campaign. Whatever they do I hope that they can keep the game fresh. I'm really enjoying it right now.
