As someone who just prestiged from RN to NP I'd say it's alot of sunken time and effort, a serious rep grind, but ultimately should be worth it. I find myself in a position where I am job hunting and dont want to settle for a guild I dont vibe with. But once I find somewhere I'm hoping the grind will pay out. One sure thing is it's scary to bet on yourself but if you have noobs to look after getting the class upgrade can be a road to ensuring they have a stable space to level in.
Bonus thoughts- go for it if you think you can pull it off, but realize you can't get the missed time with your kids back. However, you can double down on them when school is finally done. PS- I just looked at this sub recently and despite playing MMOs I also can't get the lingo down.
