I read the 2nd part and had to facepalm. Reward for showing up? I mean, if I am not enjoying the game, why the hell will I log on to claim rewards that I will probably won't use? I think LOTRO had implemented something similar also. I enjoyed LOTRO when I used to play it. I don't play that game anymore. Do I log in to get daily rewards? No.
Very true. I think ANET went really too narrow with skills. In GW they had too many to deal with as their business model of standalone campaigns ended up creating duplicate skills. In order to alleviate that problem, they narrowed the skill selections to way too few.
However, more than the skills, I think the real problem is the battle mechanics. Zerker meta can't be changed untill and unless ANET takes a hard look at their mob designs. You don't need to use innovative battle tactics or setups, when all you need to do is to hit as hard as possible.
