Guild Wars 2

It feels weird to level at the same rate each level rather than more time for higher levels, it would be my suggestion to change this, however this is a comment. My actual suggestion:
Add more levels maybe to 100 or 120 as “prestige” classes or even still regular class, but have the levelling take more time per level to reach so it’s actually a challenge, not that you’d have to grind, but a certain amount of work needs to go into it to get the extra levels.
I find the current levelling system to be too easy, I found I was climbing levels with almost no effort and I wasn’t grinding at all, I feel it’s too fast to reach max level.

having 6 lvl 80’s and 2 half way there, i think its a terrible idea, a lot of people already find it to be a grind to level multiple characters.

GW1 was perfectly fine with the level cap, same for GW2, it’s a very stable mechanic and i hope they don’t ever consider changing it without a VERY good reason.

Even with expansions, I’d actually rather have expansions similar to GW1 (although the magnitude of those expansions in comparison to the base game would be HUGE therefore not really plausible) versus getting a higher level cap.

The whole concept of Guild Wars and Guild Wars 2 is that the statistical max is easy to reach, and grind is purely for appearance. Now, I don’t know if by “prestige” levels you mean levels whose only purpose is prestige, or if you’re just referencing DnD, but suffice it to say, I do not agree. If you want to show off your ability to grind exp, there are plenty of items you can craft with your spare skill points, not the least of which are legendary weapons, which require an additional 360 or so skill points.

Anet has stated that they’ll be aiming to building more skills/weaponsets for player use but are unsure of when/how to add them (most likely in an expansion which may come with LS or through a box).
