1. GTDC is completely well balanced: random pull, short range (really it's free immunity for opponents good only for farming pugs).
2. WL pull. My main side is destro. Characters on destro (have a lot of them and a great deal of game time on them) have practically never felt WL pulls.
Probably because use requires: pet (alive pet), tactics to pet and pet without bug.
As for me completely WL pull does not require any nerf.
3 Mara pull. Total madness.
Every mara has access to it, requires nothing.
Sometimes in a bigger fight you see 3-4 mara pulls on the same target

I know it's not a typical channel because it doesn't have initiating dmg (choppa/sl channels) or immediate effect (choppa GTDC).
So using intterupt or possible disrupt doesn't contribute anything because the skill doesn't get a CD.
There are two solutions to stop this sick situation.
1. skill will receive incjuring dmg plus small dot. when it is interrupted or disrupted it will receive CD.
2) Skill will work as now but will be as the last skill in the mastery mid tree in place of Wave of Terror (I have no idea what to do with Wave of Terror - maybe Core ability?). This will cause it to require a specific build and reduce the scale of the problem.
