I don't think Guild Wars 2 is that brilliant... They took Guild Wars 1's
There's your first mistake: comparing it to Guild Wars 1. It seems to me that almost all of the vehement complaints about GW2 come from GW1 players who were expecting more of the same.
It's kinda like all my comic book nerd friends who go see some movie based on a comic and say "Man that movie sucked". I thought it was awesome! But they came in the door with preconceptions about what it was going to be like and left disappointed that it didn't match the comics. I think you'd like GW2 more if you stopped trying to compare it to what you thought it was going to be.
I was very disappointed to see bla skills and NO HEALING CLASS basically.
Not sure why you think they have "bla skills". Knockdowns, knockbacks, teleports, ranged AE, PB AE, line AE, etc -- they have a pretty complete set of "things you can possibly have in an RPG".
No healing class (and also no tank class) is a design decision some people definitely won't like but I personally think it's brilliant. The old "healer - tank - DPS" formation lead to boring gameplay all around, IMO. Even in PvP you knew you had to deal with the healer and if you didn't, you lost. Tended to make all the combat very predictable. I find combat in GW2, both PvE and PvP, to be far more active and involved for all members. Everyone is responsible for their own survival because there's really nobody out there who can do it for it for you, as in other games where you basically just got hit and did nothing in particular about it because it was the healer's job to play whack-a-mole with the health bars.
But more on topic: Hopefully they don't let P2P get people OVERPOWERED items, hopefully it's just better items or cool skins, etc. But this is a free to play game, so how are they going to make some more money?
You'd be surprised how much money people put down on cosmetic items. I thought Pirates of the Burning Sea was going to die shortly after launching "free to play" with a cash store for cosmetic items but apparently it did so well, they actually expanded the development team and started hiring again. There's money in there somewhere.
Another interesting thing here, though, is that there's no "pay to win" because there's no "win" that I can see. In WOW, Rift, WAR, etc, there was a PvE progression and you might say you "win" after you got through that progression, which was necessarily long and arduous (grindy). People would be pissed if you simply sold the end-game armor for money because the grinders would feel robbed of their "job" of grinding for gear.
As far as I can tell, GW2 gear hits a plateau right at 80 and the only thing after that is cosmetic stuff. So basically either you have fun and you keep playing purely because you find the game fun, or you don't have fun and you stop. No more of what I see too much in those other games, which is people apparently not having much fun but playing anyway because they really have to get the +11 additional STR from that next helmet in the next set. Since GW2 is free to play, they have no reason to build the usual "carrot on a stick" system that keeps players logged in 10 hours a day, 7 days a week for two years. You play til you get bored of the content and then you do something else until the expansion comes out.
Personally I think World vs World is where it's at and is where I expect I'll be for at least a couple months.
