why do you have the same thread posted five times?
and why havnt 4 of them been deleted as spam?
as for your question ive pretty much said the same thing. You should be able to choose your perks and/or how many are on the map but that may get dictated by said map. for instance, MotD probably couldnt handle more than 5 perks while nuketown easily could handle all except like 1 or 2 (im pretty sure theres not enough spawn points. but if you were to have more machines on nuketown the frequency the spawn would have to be quicker)
