Feature to STOP XP

[Rarehero]

It'd better to scale the old instances for high hevel-players. They are "skirmished" anyway. Just add a tier with enemies who can challenge a group of high level-players.

The pro:
- Player's won't get into a situation where classic instances are to easy for them. An XP-brake would be a temporary solution, but sooner or later they will continue leveling and we'll have the same problem again.
- Tons of "new old content" which is worth a replay.
