done heroic SP today.. was quite easy. Also have done BM loads even before i joined this guild.
According to wowwiki the easiest heroics are Ramparts, underbog, slave pens and mechanar. I beleive that when the gruntz finally start organising some runs it should be one of these.
In terms of gear i think we should all have a set of spec- related lvl 70 blues and one or 2 pvp epics and we shud be fine.
Also, its incredibly hard to pug for heroics unless you do the daily.
