Something i've been debating a bit recently based on the current 10 man content especially is what is the right set up for a 10 man group?
Is it 2 tanks (with at least 1 having a good offspec dps) 5 dps and 3 healers (with at least 1 having a good dps offspec)
or is it 2 tanks (with at least 1 having a good offspec dps) 6 dps (with at least 1 having a good healing offspec) and 2 healers
For the most part most fights need 2 tanks except a couple really. However most 10 man fights seem much more designed around 6 dps and 2 healers. Last expansion we mostly ran 3 healers and dropped to 2 on certain fights, but now I'm noticing we go through pretty much every fight only using 2 healers. Now i've not experienced terrace of the latter part of hof yet on normal or done any heroics so maybe this changes, but right now when we're looking at recruitment I think it is important to be clear what we want from a new player and that is, do we need a dps that can heal sometimes or a healer that can dps sometimes?
This might be sounding like a silly question, but since blizzard makes their 25 man design quite clear with raid finder being 6 healers, 2 tanks and the rest dps. Obviously most guilds tinker a bit with that, but the difference of 1 dps or healer is less dramatic as you are only changing 1/25 players rather than 1/10.
Sorry for seeming to ramble on but the correct balance of healers in 10 man always seems to be a strange one to me.
