Expand character progression
I actually don’t like talent trees and whatnot in most MMOs. I dislike the idea that I have to be really high level before I even get access to some of the cooler abilities; GW2 lets you use all your skills by level 30 (when you get elites) and I like the fact the game isn’t always about getting some new ability. In many MMOs, this feels really forced anyway, like the devs really, really wanted to come up with new abilities and were all… hmm, well, we did fireballs and iceballs, so… errr… frostfire? Yes, this will work!
That being said, more variety is always good, but you have to realize something like this would take massive amounts of work. Not only would you have to come up with huge amounts of abilities for each class, you’d have to keep them properly balanced too, plus create animations and whatnot. I just don’t think this is plausible, sad to say.
More progression is not needed, only more customization.
The thing i would like to see in the coming expantsions are new skills for each weapon. This will give more freedom in building your character like in guild wars 1.
The progression system you suggested i’m not a fan of, simply because people that only PvP will never note the progression at all and i dont think it’ll add more customization, which as the poster above me stated is what we need.
