I refuse to tank it because of the low success rate, and the many times I get 5k under dps, and can't kick them. Remove this horribly long, boring, sucky, and dull heroic. Thanks.
Make your own group in trade. You will get a bazillion whispers if you go "Tank, LF3 6K+ DPS and a healer for heroic random"
A good point. Forming your own party can take the guess work out of running a random heroic dungeon. Merely because the dungeon is itself random, doesn't mean that you can't form a guild group or gather players of like mind to run a random with you.
