The thing is if multiple people survive then no one gets a level so really you want it to be 'easy' for the zombies or no one will progress also without prestige ranks what is the point of grinding/playing infection if you get nothing for your hard work?
The goal isn't really to be the last anymore, it is to get as many rofls as possible, each kill you get now rewards xp.
Support for 1 and 3- but donor kits should really just be removed. Anyone with Elite+ is nearly impossible to kill once they start rofling
I am elite and I die frequently even with gapples, I do agree that gods and titans are over powered though.
