Good observations about the imps, thanks.
While we are not yet able to reliably clear MC to domo under 4 hours (we do it most of the time, and we, for some reason, don't try to really improve on our time), we have pretty high dps in the raid. So imps don't stay up for long, as you mentioned. I definitly agree on the "dieing is part of the job" part

I think I experienced three or four no-death runs through MC since we started in october (with wiping at Luci after 3 hours of getting there

). Good thing plate repairs are cheap...hey, wait a second!
And Lava Packs really are a pain, especially with lazy/unlucky warlocks, one of our own almost started crying when he got flak at TS for not banishing. Stupid mob had resisted three in a row

. Note to self: more than 2 warlocks help, Garr was fun with two shaman offtanking.
I'll add a "Offtanking at bosses" part to it in the near future, since that's were a few painful mistakes are possible in my experience.
Mostly burning Intimidating shout before Luci, not getting permastunned by Gehennas' adds and why not to tank Domo adds in the fire pit

thanks for the comment
take care
