fighter is arguably one of the best classes in PF2e full stop and they don't have any inherent supernatural powers. just say'n.
I don't have any familiarity with PF2e, I thought about playing PF v1 for a while but then 5E came out. But I can talk about 4E fighters. A lot of people said that about 4E fighters as well. I just disagree and no I'm not going to argue about how their powers were clearly labeled "martial".
There's nothing wrong with wanting different options for classes, I just have no problem with fighters as they are and would happily play another one given the chance.
