I personally don't think that the party set up in pf is that bad, nor are most people that picky when it comes to role selection, are there pf's that do have 1 job per role, definitely, but I don't think it's that rampant that they would need to change the 1%. If the 1% wasn't there that would probably for those people who do pick 1 job per role to complete exclude range physical in their parties. There's already debates on if it's even worth bringing physical range in higher level content as it stands because of the low damage. Without that 1% buff why bring them when you can just bring 4 Reapers and just utterly destroy the boss or if up time is an issue just bringing 4 Casters. People are always going to try to have the best party set up when making pf, removing the 1% is just going to push it into another direction of exclusion.
