Gw1 to Gw2 and the future.
ANet went with Elite Specs for profession development. They’re not going to throw that all down the Mystic Toilet to put in dual classing such as was in the original GW. Given the time between balance passes and the complaints that that is too much time, I don’t think the player base has the patience for exponentially more build options — which could of course cause exponentially more balance issues.
Elite specialisations seem to be their compromise. Each one adds a cross profession skill type. If you’re hoping for a rebirth of touch rangers or warriors with pets or whatever, I don’t think they’re going to blow up their whole system any time soon to implement anything like copy-pasting whole profession skills or mechanics.
Well its the second expansion now. There’s every chance they’ll call it quits and announce GW3. Just like last time.
