I strongly believe that for this game to retain high-level players, something needs to be done to enhance the game and to provide more options for them. What happens at level 200? No more levels, no more skill growth, etc. Nothing more to look forward too, after how many months and endless hours of effort?
I propose that Funcom adds another 100 levels to move the cap to 300. I also propose that the amount of XP required to increase from level to level be signigicatly steeper than from 1-200. Part of the problem now may be that higher level monsters just give too much XP which makes it so easy for people to level up. Some may disagree, but if 200 really was the desired cap, then there should have been very very few who actually got close, or attained it.
Funcom could add a level 275 dungeon in the temple at home. Maybe make the boss room level 300.
It would have great, rare loot but it would have to be insanely difficult even for multiple groups of level 200+ people.
Add new weapons and new monsters.
This would be a great booster pack.
