I'm curious how other raid leaders organize the classes within groups. Obviously specific boss encounters encourage interesting optimization tricks, but I'm much more interested in general purpose raid design. If you're setting up your raid for DK/spider/abom/etc trash, or AQ trash or some other general purpose, what group arangements do you find work well?
After searching a bit for related topics, I found this old thread, but many of the raid screenshot links are dead:

I've tried the 'just spread everyone out evenly' type approach - and while this tends to work, it strikes me as very inefficient, and I dislike it.
Personally I'm a fan of 3-4 tank groups: war/priest/pld/lock/other (usually rogue for shout). I prefer self-sufficient groups because it cuts down on setup time - no need to tell folk who they're healing out of group, for example.
For the rest of the raid, I like to think of 'ranged' or 'melee' groups based on the assumption that these roles will generally have a lot of spatial correlation and hence the assigned healers will not often be out of range. I.e. the ranged healers stand at the back with all the ranged, the melee healers will be in range of all their assigned players at the same time.
For a while I was assigning dps wars with rogues, but the healers complained specifically in Naxx there is a lot of 'splash' damage on the melee and it's hard to keep heavy melee groups standing. It seems that assigning 2 healers to melee groups would be efficient. Something like priest/pld/war/rogue/rogue. Do folk use this kind of group, or is it too hard to heal?
For ranged groups, generally it seems fine to give them one healer.
Our raid tends to have a lot more druids than average - like 4-6 depending. What is the optimal healing assignment for a druid? Some discussion with the druids indicates that based on the length of their heal cast time (lack of a 1.5sec heal) it is better to give them a tank who will soak damage for a while and then take a large heal. Also, swiftmend is nice for emergency tank heals - where would you put your druids?
Do people stack hunters in a single group? Do folk have much success stacking healers in 'heal' groups? Do you stack tanks to optimize imp/aura/totems? e.g. war/war/pld/priest/lock?
A couple of raid group snapshots might be helpful - and maybe a little discussion as to why specific group makeup was chosen.
