Hi i am Vulture,i would suggest to decrease the cool-down of the VIP players repairs and refills.
as the VIP players know when they repair a vehicle,refill their health and armor they need to wait 10 minutes to do that again (and sometimes you refill health and can't refill the Armour after that for some reason) so my suggestion is to decrease it because the time is long maybe 6 mins or 6 minutes and a half second would be ok.
This was my idea i don't know about the others opinion
Hope you like my idea.
Thanks For Your Support.
