I'm glad that GW2 is a bit more complicated and gives us more possibilities (even though it has not nearly as many skills as GW1). I don't think it is as "Mathy" as it seems in the first place, it just takes some time to come up with something nice because there are many interesting builds and stat/equipment combos. And thank god, it's not possible to ping builds in this game.
Dont forget gw1 at launch actually had fewer skills than gw2 at launch.
Reason they do that is because everything is so easy in GW2 there is no need to do gear checks.
And alot of people (myself included) see a lack of skill/experience in people who want to do exactly that.
