I had issues with my VW until I realized his threat aura or w/e was toggled off.
He can’t really hold aggro on large mobs but he works perfectly fine when I need him. I also make sure to ramp up my damage and not let loose when I use him to pull. He is easy to keep healed.
He’s tank-y but he isn’t a tank and won’t be able to do the same things a tank player will do.
