Support. I 100% agree with removing XP gained from kills as I got bored of playing because I levelled up way too fast.
Anything that hasn't been mentioned in the kits should not be included, if the administration team include anything extra in the zombie prestige kits without consulting the players first then they ostensibly want Infection to die again.
I totally support. It would, in my opinion, bring back most of the people that played infection, and maybe even a little more!
