If Benny Hill played Rift he would have picked a Purifier.
Firstly, Purifier with some basic pvp nounce is utterly broken in warfronts. I have macroed all my cooldowns on top of a healing flare, one macro for me, one for other people. I can run across entire maps, vaulting walls and U-turning while spamming heals without ever stopping (until I eventually run out of mana). The guy I play with and I did some Whitefront(?) Plains maps today and we lost 2, won 5 with him scoring at least twice in every win. Our wins were all 3-0 despite some people on the Rift forums already insisting the only viable strat is to score once then turtle. Also we were 32 in a 30-39 battlegroup.
People are really bad at snaring, I don't think anyone mana drained me, people don't even move well so turning 90 degrees is enough to shut down the keyboard turning Champion chasing me.
And the heals really over power damage unless we're massively out-numbered. Quite a few people don't seem to be able to hurt a moving target anyway, I guess relying on slow cast spells. It's really easy to neuter Sabs and dotting classes because unlike WoW the decurse button lights up if there's something to decurse. So it's Pavlovian - button lit? if yes, press button.
Much to their surprise, Saboteurs are unable to one-shot me.
Also people don't know where the power-ups are, one time we went through a 5 v 4 fight at the base entrance, ran past the 3 guarding the stone. I shielded him so their attacks failed to interrupt, then he grabbed the stone, grabbed the nearby speed boost, ran to the middle for the next speed boost. They left him to score while wailing on me 3 vs 1 but I just tanked them and ran across the map. Eventually they gave up for easier targets. I mounted up and rode across the map eventually catching my partner at the turn-in point.
In pve instances things are tougher. I find it rather hard to solo heal. I can just about do it but I really miss a heal my tank + heal the dps too. Because my best heal is a 3 second cast if I am casting on the tank and a dps spikes low I can't really do much. I'm committed to the big heal, throwing a 3 second cast on a dps then going back to the tank means a 6 second hiatus which I'm not always willing to do. One poor guildie died to all 4 bosses in FC. (In my defence he was a little under-level, the impregnate from the spider practically one-shot him).
It all becomes cake if I have support. A bard or a second healer makes life so smooth.
So anyway if you pvp definitely recommend Purifier, having an utter blast with mine.
