This thread you can rating general at the rank from 1 to 10 and following suggest to improve them.
For example :
Grey Tanker : 6/10
_ Need better opening (
Your opening here ... )
Mouse : 3/10:
_ Improve late game ...
Black Reaper: 2/10
_ Faster rush, should target probe, not building ..
Ofcourse don't need to rate all generals, maybe the one you really favourite or the ones that too weak, need to improve.
