I dont know if it's been mentioned before but how about a variation of Blitz and have a speed round?
When you select blitz, select 30second clock = speed round?
Yes a faster round,but all that really does is speed up the slower players. I mean a game based on speed and accuracy and combine the two for points.
Blitz is meant to be fun but far to many people take it to serious and take up the full colock!
