How about a new Assist potion/skill?
Uber/Super Assist
Level 250???
+0.05% per point chance of one of the Top 25 players assisting in combat vs. creatures. (Player is randomly selected and adds 50% of their attack, defense, damage, armor and hp).
Duration: 60 min(s)
Or instead of Top 25 players, you could make the % a bit higher, and select from the Mercenary pool.
I dunno, maybe stupid, maybe not....that's why it's only a suggestion
