Pre-made’s are always going to destabilize the balance in Hunt, the advantages of communication and familiarity are not likely to be over come by a damage change or health buff.
The simplest solution I can think of is giving the same advantages to the Pred side and that means adding a second Pred. This will change the balanced of the Hunt, it will be a Pred favouring mode for those who wish to chose it.
Basically if a Pred player chooses, they can request a second Pred player join the lobby (hopefully lower que’s). Anytime a Pre-made team of sufficient size or win ratio, enters the lobby you’re given the option, if you choose it, a second Predator will join you on the hunt.
Nothing else will change other than the second Predator, the team will only know by checking their map.
So what do you think? Would this help the balance or utterly destroy it.
