every other mmo has a "dps to heal" class. they all work the same way. they dps, the server picks who it heals. they are afforded limited control (like setting a beacon on a tank, putting a statue down somewhere, whatever), but they are "smart healers".

Smart as in, the server decides.

Because of the limited capacity to make decisions about their impact, they are typically considered a "support class" and not a main healer. that doesnt mean they cant put out throughput higher than any other healing class, it just means they are support and not directly responsible for monitoring and reacting. That job always goes to a main (pure) healer.

First off, you overstate your case. Not every MMO has a 'dps-to-heal' class.

More to the point, to fit in WoW, monks need to be able to successfully heal 5-mans as well as handle tank healing and raid healing, even if others are somewhat better at some of these tasks. That is, they can't be ONLY a backup healer. If they can't main heal, too, then the spec fails.

We've already seen the existing healers get nerfs because too much of their healing is 'smart;' in fact, we've got more nerfs incoming in 4.3 for that very reason. No way Blizzard is going to base a class's heals exclusively, or even mostly, around smart heals.

And they've already told us they like the current healing model, which among other things means mistweavers are surely going to have a slow, weak, efficient heal, a fast, stronger, very inefficient heal, and a slow, very strong heal, all directly targeted. Admittedly, they could turn out like druids and only rarely use the baseline heals.

no boobah, dps to heal doesn't work like that at all. I have no idea why you even think it could possibly adhere to that model.

Stop trying to pretend the mechanics are somethign other than what blizzard already said they are.
