Has anyone ever heard of
Rune: Halls of Valhalla? That is an example of a PvP-only RPG. Guild Wars is that and more, and they draw a PvE crowd and a PvP crowd.
Lyra wants the two to come together. I don't really PvP at all, and I say there's little wrong with them being apart. Someone who only enjoys PvP is not going to want to play PvE just so they have equal footing. In fact, that is what the whole kafuffle was in the beginning when there was no such thing as Balthazar faction and anyone who wanted to PvP had to suffer through the campagns. The ability to make a PvP-only character right off the bat is a fully implimented and fully supported feature. If they have a disadvantage, then what is the point of having that feature in the first place? Truely competitive people, of the type who only play PvP, would not want such a disadvantage, and if they have to go through the entire PvE campagn which bores them they are not going to stay with the game. There are other PvP games out there, after all.
PvE is not there for the sole purpose of supporting PvP either. It is not a means to an end; it is a purpose in itself. I
like playing PvE. That is why I play it. That is why many people play it. One shouldn't think of PvP characters as a free ride because PvE is simply what we do to pass the time. PvE characters should have no advantage over PvP characters. The "work" they put into their character is the reward itself. If you don't like playing it, you shouldn't be forced to do so just to get to the game you do like playing. This is a video game after all, not work.
Those of you who say PvEers should be rewarded for their "work" are missing the fact that we already get rewarded. We get our fancy-looking armour, our titles, our weapons, etc. But if we get a PvP advantage for our PvE efforts, then that is the same concept as WoW or EQ or all those other MMORPGs which grant advantages based on the time a person has put into a character. ANet has openly and frequently put down this concept and claimed that their game is different in this respect.
As for whether or not this game is an RPG, that doesn't have any relevancy. Nobody should care under what catagory it falls. It's a game. Do you like it or not? RPG is a rather broad title these days anyways.
And just because people will always find things to complain about doesn't mean every complaint should be ignored.
