I have had bad experiences with hiyru's, the massive cold resist weakness makes them bad against wither and hailstorm. Mayb it could work at yew gate, but I havn't seen a great bok hiyru combo since they nerfed it years ago. It used to be the best, it would dismount all the time and you couldn't break the nerve strike para. Cu's are great tanks, have great cold and energy resist, so are nice for the grinders and of course heal themselves. Dogs do seem to be sparadic with damage tho, I've had dogs chomp a guy 3-4 times in a row and drop him, and I've had dogs miss 10 times in a row and make me look silly. Overall tho I think dogs are better, the ability to cure/heal themselves mixed with bleed is better then the hiyru imo. As a bush tamer you don't need to rely on the hiyru to dismount, because of riding swipe, so I don't see any reason to use one. It's been so long since I used my hiyru, do they still give you a dimount timer in pvm? Yah that was the one that did it in for me, I would have to wait all the time to get back on my pet because it was dismounting in pvm.. which didn't actually do anything.
