the reason why people get confused by it is that if you spawn on the middle platform (not the high one) inyour base, then there is really not much way of telling which way to go for the high and which way to go for low. Maybe make some signs. I see countless newbies running around trying to find an exit to the base without getting distracted by 'ooh! a ladder, I'll go up it' and then 'oh, this is where I spawned again' only to be greeted by a guy with an autococker. They then die and then disconnect.
Another thing: PLEASE get rid of the autocockers at the high. Its ridiculous when 2 n00bs get them and spray the entrance to the high when you only have a trracer

EDIT
before you flame me for reviving this topic: I havn't been on the forums fora while and I really want to see this get implemented so I thought I'd contribute my thoughts!
