It not that warriors don't tank its that they can't

[Rare]

Its about getting aggro and keeping it, chest splitter itself is weak in terms of spec and overall usefulness. Since it doesn't work with most bosses and has limited range for mobs.

The cooldown time is very low... so keep using it. I'm not sure what's weak about it. It takes aggro. LIke I said, slice it how you want. I haven't had problems with it (then again... I'm only speaking for experience prior to this campaign). Sure with the occasional maxed rogue that really knows how to dish it out it can be tough. But honestly, there are very few relatively speaking.
