I just checked the whole idea. Shock you are giving well explained and amazing ideas. In addition to your idea I’ve been thinking about those skills (dot,stun,slow and other) and they could be added into a smaller pet talent system or something like that where you can make different combos of pet spells. This way the PvP will get even more interesting due to the amount of all combos possible.

This will be too much OP for some classes and will give us hell to balance the game.
