Tower design questions and observations

[Canaris]

I just finished watching the epic TB/Higby live stream, going to have to watch a few more times to get all the nitty gritty details to dissect

One thing that stood out was the tower design from what you showed and this topic is merely based on that, I know it was probably not finished but it seemed like the jump pads for access to the higher levels was on the towers outside, those white platforms?
Would that mean forcing attackers/defenders to the outside of the tower in order to go up and down would make them vulnerable to fire from well everything negating the towers protection.

Veterans from PS1 will remember how tower battles unfolded, drawing aircraft and vehicles like flies to dung, if you were infantry and outside the most likely thing to happen was to be blown to pieces, the tower doors were your friend.

Also a lack of a backup normal stair case access to the various floors, seemed that you could get to the first floor and no further do you think it will cause problems in tower fights for ease of access?
My concern on seeing you can only reach the upper floors by "grav lift" is it might lead to lemming effect as the troops go up the lift single file there could be simply enemies camping the other end with fast shooting guns with lots of bullets making it as TB said, a meat grinder, to rival the bloodiest tower battles of the PS1.
