I was trying to think about how this could be done and I think I've come up with an idea

a 10 point root ability for clerics in the PVP soul that upgrades your current dispel to dispell +1 negative effect. so instead of just 1 charge it would be 2.

That way you'd have to dedicate a large chunk of points into the soul to get the benefit. you wouldn't be messing around with Cleric or Rogue GCD. and you'd be able to do this pre-50 because you can put 10 points in as soon as you unlock the soul.

This almost seems too good to be true. What am I missing here?
