Prepulling mobs as healer

[SamRF]

Edit:
Please don't bother replying if you're just going to ignore the situation I described in original post. I'm not saying prepulling as healer is always okay, only in given specific situation.

Conclusion?: Reading this thread I see why the community is against this, even though I don't understand it, so I guess it served its purpose. I think I may not fit well in this community which in the end would be my fault and problem, not the community's.

I won't be surprised now after this thread. Just completely didn't understand why you'd get upset, cause I really don't see myself get mad in that situation as tank (I main tank). Instead of getting upset I'd say: "sorry for pulling too little". I don't feel entitled to determine the pace and amount of mobs as tank.

Original post:

If you know the dungeon and have an idea of what's coming and how much damage there will be dealt, there's imo no point in not rushing ahead and pulling more mobs as healer when tank keeps pulls small, especially when tank is geared to the point you barely need to heal. Me and many other healers/players are constantly calculating which move will lead to most dps while keeping everybody alive, and rushing/pulling ahead is sometimes the best move in that regard

I usually don't prepull even when I know I can without problems, except for some cases, like in those lvl 50/60/70 dungeons. Sometimes I literally have to use maybe 5 healing abilities (oGCD/GCD) throughout whole dungeon even when tank pulls wall to wall. They are an absolute joke to heal through and thus they are very boring as healer cause you're stuck spamming 1 dps ability all the time.

Yet several times I've heard tank or dps get mad and tell me to stop prepulling, even when they had ignored my request to pull more. Meanwhile tank proceeds to not go beyond 80% health without any healing. Why is prepulling considered rude/bad in this case? Everyone is completely overgeared to the point they may solo the entire dungeon.

I don't mind at all if tank wants to keep pulls small, but they should also not mind if I go pull mobs and bring them to the tank. They literally don't have to do anything except their aoe rotation, which they are doing anyway.
