Karazhan the Group-breaker

CD's starting to make some decent progression in Karazhan, having killed the first five bosses. As it stands though, we're in a frustrating situation, since ideally we need people in the following roles to do a Kara run:

3 Healers
2 Tanks (ideally at least one is a Tanking hybrid able to take on another role in single-mob enccounters)
5 Damage Dealers

Given the large amount of undead in the instance, then it's preferrable that at least one priest is amongst either the healers or damage dealers.

Currently, CD has the following attuned and willing to go to Kara:

8 Healers
5 Tanks
23 Damage dealers

Allowing for people to have night offs or unforseen circumstances, we barely have enough tanks and healers for two runs, whilst we have more than enough damage dealers for four. If Karazhan was on a 3-day reset timer (like the old 20-man instances) then we might get away with running two groups. Given that it's currently on a 7-day timer, it means that anyone who goes to the instance gets tied there for the rest of the week and can't enter another version.

It all smacks of Blizzard trying desperately to eke out raid content until it could finish the later 25-man encounters. But it's playing merry hell with our group at present.

As a result, our healers and tanks are tied into going most of the time and burning out as a result. Also, a lot of our DPS are being left out of the runs and are similarly getting burnt out and left to feel useless. If this coming summer's anything like last one, then we'll have a lot of folks away/on holiday/enjoying the weather, and those of us left will have to try and muddle through regardless.
