FUCK NO!
Last one ran for 9 months.
The one before that ran for what, 6 months?
The last two CUB events were one of the reasons people left the server because they just kept on running and nobody was here to fix things.
There is an over flood on CUB items; they sit in vendors for months and nobody buys them; why would you want to add more?
Have you encountered that kind of lag and long world saves CUB would ACTUALLY help lower?
Keep in mind that there is way less players in the shard than there were a year ago which means there are less items going to be removed and it would affect less to the server.
If they did an event where you'd get rewarded for tossing in actual lower end handouts; shirts and sashes and stuff; that'd be cool. Nobody ever uses them and they count towards the item count. Before CUBIII Ryan said they would be a better rewards for tossing in semi rares but that didn't happen.
Just a bad idea IMO
P.S. You should've made a poll if you want votes.
