isn't there also some slight verticality differences between the two bases' interiors? I mean like accessible ledges and the like. Also, doesn't jungle have windows in the front walls in parts?
I honestly have no clue. The issue isn't inherent to one map though, it's going to be a universal problem anytime you try and play infinity slayer with a team that understands how it works. If you don't give teams any reason to move and literally deliver power weapons to their position, you're not going to have teams moving around.
