Bumping the idea of cs maps only bomb server. Since you edited inferno and it is now not only playable but looks better and better every beta release, there are 4 maps to add to the maprot without any doubts:
ut4_inferno_b8_dswped
ut4_dust2_v2
ut4_train_dl1
ut4_cache_b6
And 2 on the sub bench:
ut4_dust_a4 (no locations) <-- fix it?
ut4_aztek_b2 (it's a bit narrow, so actually f2 here?)
Why?
1. these cs maps are very popular and have layouts designed for bomb mode.
2. look at dust2 only server- you could 'stole' some players getting maybe bored with dust2 only?
3. you don't risk much, dswp bomb 7vs7 is recently unfortunately often empty and you keep 2 tdm empty servers ( replace 1 of them with new bomb one?)
4. don't be late as someone can steal this idea
Call the server some funny name like: CAMPER STRIKE dust2 inferno train cache...
