I need a new level cap too if i think you add New gear ( different looking armors and weapons for any class)/ New map/ A few new strong enemies/ Arbiters etc. to the game. I know it will take a while and its hard work (alone?) but the time to wait will absolute worth it. At this time there you produce all the new stuff, you could make some other small events like the latest that many players liked so much .
I miss the kills you could get at any area tho...but i guess we cant get both...
