My 2 cents on an upcoming patch:
First of all, thanks IW!  I had thought that the most recent patch might be the last and that you might be moving on to your next game.  This will be a treat 
 
As for suggestions, two things pop to mind:
- Increase the Global Spell limit (or make it a game setting), for huge games.
- Fix the Dome Stacking Bug 
wait did they fix dome stacking in the last patch?  I havent tested it...
