Just started, and gonna be PVE centric. Some advices?

I'm usually a big metaslave, bc I just like to shred through the game, what Karmas are currently the best for PVE? and what status distributions should I go with?

From the little I've got so far, is that Blazing Fist is the best breaker, and that you should probably go in with a breaker and a slayer. I've got no idea what the strongest slayer is for PVE currently, or if it's just mainly by your own tastes, the Dual Soul does seem somewhat fun if that's the case.

I really wanna know about the status distribution since I do not wanna fuck that up and have to rebirth, reset or whatever it is later.

Is there any guide specifically that I should look up to get the game at first, or can I dive in without much worry?

Considering it is a KOG game, what are the pay to win microtransactions of Kurtzpel?

Would I be able to play through the whole thing solo, or will some of the content wall me out, and have me team up top be able to proceed?
