Sounds..uhm...well sounds like a wipe...tho grull seems easyer thn the first guy...i'm prolly wrong...anyway i'll prolly need some qs in there...its best for people to do "The tempest key" attunement...as far as i remmember u have to go to Grull's lair for every other instance that needs attunement (meanin 25 peeps instances)
Dunno sounds fun and i'm sure up for it...but i think peeps need to start doin some attunements...meanin not just Karazhan but some other too (includin gettin key that open heroic mode for instances)
Just my idea
