Remove XP capping for level 20 and 30.
So for example you could be level 19 reached XP for level 20. But not capped until reached XP just under level 21. You wouldn't have access to epic destinies etc.
My toon just hit level 30 I haven't taken the level but capped. I don't see why this is necessary.
Would mean more people would be playing more heroic and epic quests.
