All kings forced pops? I'd like to get a claim on one some day but don't see it happening with all the claim bots that are still out there.
Increase probability of getting Rar/ex item after every kill of an NM so you dont got 0/60 trying to get a pair of Okotes while some other yokel gets it on the first kill.
Make Argus much harder and make PCA a 100% drop.
Fix Nin ranged? Nin's get some of the highest DPS ranged weapons in the game. Unfortunately one of the shurikens is rare thus non stackable and another requires 2 hours worth of questing to get just 1 while the third is a high level synth and costs 100k a stack to buy. Either create more high level shurikens that are easier to craft (new synergy synth maybe?) or give nin a merited ability like unlimited shot so that I can use that rare shuriken once every 5 minutes or so for some spike damage.
Linkshell banks and armories would be nice too. Perhaps only accessable by sack holders or some such.
