A general idea could be to design a map where it is designed in such a way that the attacking team must make more of a pre-determined commitment to a single bombsite. Ie. a map that focuses less on pick and choose tactics.
To make a competitive balance for such a map you would have to do the following:
Make both bombsites equally achievable for the attacking side. (unlike most cod4 maps)
AND EITHER
Make the defence of each site easier than the attacking side. (so that say 2 defenders could defend against a simultaneous 4-5 man attack)
OR
Make it so the defence side are more easily able to rotate from each site.
The latter would probably be better for two reasons. One is that it would force more teamwork from both sides e.g, (Omg there attacking a from poopy-head road come help guys and get them from derp rooftop of w/e)
And 2 it would make for a more face paced and intense game as speed is key for the attacking side to take a bombsite before the other defenders can rotate.
