Nerf the Ghost Tank?

[TKF]

You're speaking of the ulti as he always have it on lv5, which means that the ghost tank must be lv22! I actually never seen a ghost tank in lv22, so that scenario is very rare (I've actually never seen a rush game where someone buys ghost tank). In normal combat I expect this skill to be at the levels 1-3, rarely lv4. Which means it heals 28-42. Then the ghost tank user usually switch to a stronger tank.

Otherwise I find the soul collector quite strong
