Hyrule is the best stage in the game. Nobody that shouldn't beat me(skill wise) has ever taken a majority, or anywhere near that, of the matches we've played there because of camping. Can anyone say otherwise??
Gerson won 8 matches against Isai, and Boom beat Isai's low tiers at Genesis because they are both outstanding players, not because they camped. I think I watched every single one of those matches, and while I can appreciate an action packed match, I think these matches had a special kind of tension and beauty in a lot of the spacing. Sure sometimes it would seem like both players were saying, "Nah bro, you approach me!" But that was all part of the mindgame. Can you blame anyone for not approaching Isai anyways?
Dreamland is a gimpfest. Their is no open air without platforms and No walls to combo off.
Hyrule has a good mix of a lot of different stage elements, and usually takes more than a single hit to put someone over the edge of the stage from the opposite side of said stage. I like DL, don't get me wrong, but there is plenty to complain about there too.
As far as campers go, there is a simple, fail-proof method for getting an opponent to stop camping: Berate them for being a little pansy-***.
