When you increase these caps can you make things faster for people not at the level cap to catch up ? It has been made extremely easy for new players to hit lvl 50 (often during an event within a few weeks), however, things really slow down especially in the 60 plus range.
Maybe some special quest lines to help or reduce the amount of xp needed for each level by a significant amount.
The highest person on my friend list/guild list is only 73 and they run so so many adventures. It almost seems pointless to increase the level cap actually for the few people who must be at max now.
