Guild Wars 2

Now, this has been discussed before.
But I really, seriously, truely and sincerely think there is no way around it.
If you wish to accomplish a balanced, playable game in the next years this is the only option you have left.
Actually for this balance patch it does not seem to be an issue. Seem
The problem here is: you did not do anything against the sustainability of so many classes, all classes actually. And how could you? If a class does not have access to tons of invulnerabilities, damage reductions, stability and can heal twice their health in a single encounter minimum, they will just get ripped apart by a mindless storm of aoe.
You need to tone down both damage output and denial to make this game remotely skill based, but if you did so in pve you’d have to readjust raids, fractals etc entirely.
In other words: if 2 classes both perform on 9000 its fair, but not neccessarely balanced. Neither good design.
For example player skill could only have an impact of +-50
Why not just put both back to 100 and let the players play the game, not the classes.

You said you wish to avoid skill splitting because it ‘causes powercreep’, what exactly do you call your current solution?
