I have an idea, might benefit all the people if gets implemented.
The Collector usually drops not so useful items for end game chars, less people are doing it because of this situation so how about allowing more levels to do the collector?
What if each SL zone gets its own collector instance with level lock? Consider Ely collector with a level lock of 60-120 for example, all mobs inside will scale, it will be a team instance and all the chest will contain relevant collector items to that level.
This will allow all the level groups to take the advantage of this new instance and it will drop some useful items for that lvl range.
Any comments :) ?
