Sry for engrish =)
some screenies:
Here we see some attacker-only (mostly) windows that can help them to wipe the bridge, and i suggest a mini cover on the tricky box, otherwise it is too exposed and thus rarely used trick route.
one of possible ways to get to those windows.
another angle, same *****
tl;dr
i think much more micro layout decisions for attackers need to be implemented into the maps with moving objectives (i.e. EV) so that it would be easy to build up attacking push and move the frontline step by step.
