I've yet to see any problems with my shadow as soon as I started to feed him some Ghoulash. He is only 455ish, but can easily clear visions with it. I even pull like a mad man, spaming vamp (with SW: P talent) going into voidform.
Either way, pulling much is not the "way to win" strat. The timer is a non issue as soon as you are at R15 and got gift. Playing safer is IMO the better way to deal with visions.

I've to disaggree with the latter. Even a Tank can die while staying inside some stuff - or get cc'd. Ofc, one should still playing mechanics, but I've seen some people dying to really stupid stuff.
