Finally tried out PTR. The pet issue is actually no longer an issue, the other WD pets are greyed out and do not bump into each other, or if they do it is not noticable. You get 100% out of all of the pets because they can literally focus on one target and not just stand there. I went from struggling on T4 with kill speeds to just blowing through T5 in my current gear setup.

This is a huge change in a positive aspect for Multiboxing pet classes.
