[mod]This has clearly become a thread about Rift itself.[/mod]
Good move; whilst I found it funny, the thread WAS a bit cheeky in the first place, even before it grew to this.
So PvP is just as flawed as wow then in that you need a healer to be able to contribute.
You're seeing things in rather black-and-white terms.
Warriors (assuming they had enough sense to read some of their soul point descriptions and build a spec they can play with) are pretty harsh in PvP regardless, but have little means of escape or self-healing compared to the other three classes. One-on-one, a warrior can still devastate me, and I can do the same back to him. Thing is, there's just something about warriors that makes them that much more of a juggernaut with a healer backing them up, compared even to the other classes. Do they need a healer to be effect? No. But when a warrior with Warden HoTs rolling on him comes charging at me, I know I am - at best - in deep trouble.
To be honest, Warriors have come a fair way in balance terms since release; the silly long-range extreme burst death spec was sorted to be less rediculous and actually require more of the melee they were intended for, the Titan Strike warriors still hit damned hard (as I'd expect for speccing deep into a 2H weapon soul) but are less rage-inducingly insta-gibby, and the PvE DPS warriors are by and large in a damned good place - something I'd expect for a class with no intended ranged option and fewer "get out of jail free" cards than their fellow melee clerics and rogues.
Also... yeah, Warriors may be top PvE DPS, but Rift seems to avoid the "Flavour of the Month" syndrome in PvE; I haven't seen a huge population boom in the warrior derpartment. PvP FotM is another matter (lol rogues), but I still see reasonable representation from all four callings.
