POV of Illfonic they count most as, at least at the moment, they seem to be the majority. Games cannot be balanced for the minority of top tiers, right?
But, as I said, I think the game is balanced for middle-class random FTs ON PS4 (!) too. I belong in the category of some 1200 damage points in the average (sometimes 500, sometimes 2500, often 1200…) - if you accept that to be “middle-class” - then I can say, that two to three middle-class players are enough for most of the predators (and they tend to be more experienced than FT players, if yo ask me).
So, all that buffing/nerfing thing is not the main problem. It is the matchmaking and maybe the vast health supply for 4 supports with syringes & medkits. But whether you use a GOSL or a Hammerhead does not make a lot of difference (although there damages are different).
Play random pubs NOW and tell me, that the FT is overpowered…
