I understand your concerns. However, we playtested the map quite some times at Mapcore and the feedback overall was rather good. Did you give it a go with bots?
I think you're mixing up the bomb site letters, but here's the general idea behind it. Bombsite B (the one you can get to fastest through the pillar room) indeed has only 1 logical route, but this route still needs to be covered by CTs, so it takes away a few CTs that can't protect the other bomb site. However, if Ts are able to break through this side they have a really good chance of planting the bomb on B. The distance between A and B is pretty short, so CTs covering A will get to B rather quick, but I think Ts have a good chance of defending the bomb, unless it's 5 vs 1 off course.
Long A is meant to take a little longer, but it's probably the "safest" route to A and it provides a flanking opportunity to take out CTs guarding the middle route. A is easier for Ts to get to, but harder to defend when the bomb is planted because it's more open. Put simply, this should even out the choice between bomb spots more or less.
The middle route on the other hand gives the best possibility to change tactics when one bomb spot seems to be too hard to reach for Ts.
Again, this was the theory behind it
So far all gameplay feedback seems to support this.
Rotate might be too strong for ct's?
I'm not sure what you mean with this?
Thanks for the reply! I hope you get a chance to play it somewhere and enjoy it
