Rooks towers still a JOKE
The max number of towers you can get out is 4. The damage they cause is still negligible, let me elaborate:
I was a level 13 rook with maxed out towers ( level 4 on the skill tree ) I bought up to the +20% damage + splash upgrade and the +30% hp upgrade at the citadel. The towers were hitting 100's on the nightmare level 23 regulus I was playing against . I unfotunately was only hitting 200 because I put everything into this tower path.
The towers are a completely useless skill path right now. The skill points are much better used in hammer slam, rook roll or god strength. The rook is a one build guy right now. He needs some work to impliment his other skills. I hope this isn't his final call right now but I hope this evidence convince the devs to do something for the rook. The towers need to have no time limit and do more damage!!!!!!!!!!!!!!!! The amount of HP the have is great if they can do more damage like a normal Tower of light.
