Hey man I'm just trying to help you enjoy the game a bit more. This lack of roles thing seems to have you upset. I haven't once called you a noob or directly told you to quit. I said the game may not be for you if you can't change your perspective. Quitting is up to you.
I honestly think you'd be happier if you would let go of GW and take GW2 for what it is. There are plenty of other issues to chew over than arguing about one of the pillars of the game. "No one profession is absolutely necessary in any given situation" is foundational to GW2. Griping about it is as useful as complaining about water being wet.
I played a feral druid in WoW, pretty much though almost all of vanilla, until I quit in Cata. Feral in vanilla WoW is the definition of going against design intent. Well, if you can call how blizz designed them at the time as having any intelligent intent.
You realize that is counter to your point right? The pawns aren't going to be whipping out any new combination of skills to take a rook. If used well they might take a rook, but both players have access to the exact same set of abilities (pieces) at the start of a match. Without even the window dressing we get in MMOs.
