LOL came up with another idea for an even for a private server.
ZOMBIE / Scourge event thingy.
Still have not gotten your attention???
How it works
Every wave sends more mobs / elites. Every 10 or so levels is a boss. And after you beat a wave you get a token such as
wave one gives you 1 token
wave two gives you 2 tokens
wave three gives you 3 tokens
total of 6 tokens
And just add 1 to every wave.
For prizes you can give away armor pieces for like 1000 tokens or so.
Do you think this is a good idea?
