I'd love to watch, I really would.  With no healers though I think it would be awfully hard not to start losing people (even one missed interrupt would have one rogue to half health, then the water elementals would surely kill someone (or two) before they could be killed.  Health potions, ftw - and if you could all get a warlock cookie, that would be helpful too.  And I suppose you could bandage once every minute for that little bit of health. 

As to the blizzard, I'm going to have to test whether it is possible to stand on top of him and not take dmage from it.  If so then that is a great strat for healers/range (and I'll come back to thank you profusely for bringing it to my attention!).  I've honestly never tried that, having done the fight on a mage, a priest, and a resto druid (all ranged).

If you get a rogue group to attempt it, please let me know, though you will have to find a raid group willing to let you take Aran after they have cleared to there, lol.  If you can capture it on fraps, even better!

There is a u-tube video of 10 pallies clearing Kara (highlights). I don't have the link handy but it is well worth the search.

1st off all palas can heal tank and dps(not rly good tho)
if rogues are good  they wont hit by single spell if one and not all of them waste kick on interupt water elementals aint hard just adrenalin rush evasion clos bit = killed
and it is very posible just sneak to him somehow (some mobs got detect)
or get raid to clean trash and then rogues come in
i will try it on Lightnigns Blade

And yes, pallies, like druids, rock for versatility.  The pally dpsers were shockadins, so not bad dps at all.  And they were all very overgeared for Kara, lol.  I'd love to see an all druid group clear Kara as well. There is a great video of a balance (Panzer specced) druid tanking Prince in moonkin form.  It's awesome. 

Please do update us on the rogue attempt on Aran :) 

10 pallys... How about an AV team? I've seen a dirty human pally survive for like 5 mins with 10 hordies wailing on em...
