Guild Wars:
Create a competitive play against the guilds for Guild Rank among other guilds. The point system would be for example:
(the guild has to play a minimum of 5 guild players
together in a match. )
Other games=5pts
UnranK match against randoms =10pts
UnranK match against Guild=20pts
Rank match against randoms=30pts
Rank match against Guild=50pts
Event games=100pts
Any loss match with guild is equal to prospective gain
This would be seasonal and reset completely after the season ends. Which would give guilds competitively fighting to be number 1 or top 10. With a winning of the top 10 getting ice. The higher the guild is in the top 10 the bigger the ice is.
