Nope its bad idea. I can see many multi clients and afkers in PVP waiting for free cash anyway people earn that cash much time (low lvls on water) why then another shall got it free?
not every 2 days 1 time a week a ticket cost 50-100hd and prize around 500-1000hd (all depends how many people enter). we have done a lottery before so i dont know why we cant do it again.
