And when I say situational, I mean overly so. The fights that have such large AoEs are way too few.

You may find situations where you find it useful (not a complete waste,) but it will always be the inferior use of BG.
Maybe I'm just being dumb here, but Onslaught is an Ability, not a Weaponskill. So you can Tomahawk then weave Onslaught in situations like that.

Hell, you could even use it on pull by doing Tomahawk then weaving Infuriate and Onslaught before going into your aggro combo.
