Change your race to nightelf and shadowmeld lol...

That racial skill has proved useful in my survival whenever I pull aggro from aoe cleaving / whirlwinds. Sometimes its not the main target that you are getting aggro from.

Especially when you charged in, deathwish and reck, then cleave + whirldwind everything is big numbers, the MT mob will still be on the MT but some random mob will aggro to you.
