yes offcourse most of the floors will be spawns
not a good idea as a spawn point uses a lot of entites especialy if u want them to be captured by both team then you need twise as many entites, 32 spawns per team 64 entites in total per spawn point, your soon gon hit ur limit doing that
and as Ifurita say
where are the attackers … did they sneak by us?"
this was that basic thing behind my idea that elivators became active taking you to higher floors faster
basicly if ur gona get this to work your goign to have to group sertain floors into stages of the map and at the end of each stage block it of but allow your defence (from above) to get past it while not leting the asult though, something like a hole in the celing or a teamdoor
then the objective for each section would be to blow up the door restricting movemet or do something that alows them accs to the next section of the tower
then the asult spawning at the bottom in the elivator halway get an elivtor activated taking them dirrectly to this next section of the map, this avoids long walks to the part of the map and cuts down on the number of spawn entites needed. the defence also need some kind of elivator taking them down to the part of the map they should be defending quickly 2
consisder for your elivators to wait in the spawn room untill activated but give say a 5 second delay on activation before they move to there destination so 1 person doesn rush out of the spawn and take the elivator by himslef leaving the rest of the team stranded
one last thing, 98 floors sounds like a lot of work, if u still want to keep the feel of a tall building you could sort of miss flors out, a staircase giving access fo 4 floors but the doors are locked so it gives the impresion of going up a great deal of floors but realy just serves as a conection between floor 4-7 ect
