Early LK, it caused (and still do) a lot of issues between groups who had someone who could do it, and a raid without. This was espcially noticiable on 10 man.
So they tried the "spread the love" tactic. Hunters took it for a few weeks, but I rarely see any Hunter nowadays who want to pick it up, for DPS reasons. Frost Mages aren't PvE viable, and Locks... yeah, I've yet to see one give me Replenishment. The only specs who bring Replenishment nowadays, are the same two specs who did at the begining of LK. Seems like this strategy failed.
Throughout LK, mana regen was "nerfed" a few times, as they wanted healing to be less spammy, while making more dangerous fights for tanks, where the risk of one dying in 0.5sec was present during all the encounter, and more fights with insane raid damage.
So they gave up on the "let's nerf" mana regen, and just allowed healers to not worry about mana. Ever. Let's not talk about the 0.25% nerf to Replenishment, there's barely any difference.
I know it's "old" and has been discussed a lot... but could we just get rid of it for Cataclysm, and make sure healers are able to heal, without spamming all the time, and do it without having to rely on someone else to bring it? It's still doesn't make sense to me, it's as if they were expecting tanks to rely on a Hunter / Rogue's Tricks to do their job.
