Great idea samo
I like splitting it up so everyone has a chance. Something like this:
1. lvl 15-25
Human, Dekans, Dhans, Mages, Archers
2. lvl 15-25
Elfs
3. lvl 15-25
Human, Dekans, Dhans, Mages, Archers
4. lvl 15-25
Elfs
Screenshots can be taken of the guild listing before the event and after. Anyone who wants to enter can just reply to the announcement. Also, records of will need to be taken of anyone entering the guild.
YOU CAN WIN
500K and a new set of Graham for each 1-4
The graham can be taylored to what you like (PD or MD)
What do you think?
