I made a post on the official forums about an ability I thought would be neat and help solve the problems we face in PVP.

The ability would revolve around a pet and would work out to be something like:

Your pet casts something on hostile target X and teleports them in a random direction 20-30 yrds away from you OR teleports hostile target to your demonic circle (40yrd range limit of course).

It didn't receive much attention though.
