What FPS skills? You mean those FPS skills that are needed for farming lobotomized bots. Because bots make up the majority of your targets.
Don’t act like playing infantry in Enlisted is some niche thing with high skill cap. It isn’t. It’s just as much braindead as annihilating bots with HEs. (Not to mention that building rally points actually matters more than your KD)
That’s why I like Enlisted so much. It’s a very good game for chilling out.
