Not necessarily. Horizontal progression is MUCH more interesting than vertical progression. We already have ZERO character customization - increasing the level cap without adding some form of horizontal progression would only make this worse.

Not to mention the never-ending cycle of obsoleting your previous gear is REALLY annoying. Quite frankly, I've done that non-sense now in several other games. I'm barely tolerating the silly gear treadmill they currently have us on. If they exacerbate that by releasing a level-cap raising expansion less than a year after launch, that will be the end of my sub, period.
