Need some help getting re-started

[Raldo]

Anyway I read that some people said Monk is the best for end game etc and others said Summoner was the best, just curious. Also they are all different characters and I was wondering which ones to stick with. When I made them I was just trying each class out.

If you're going to be a hardcore raider (i.e. dedicate many hours, generally with the same group, dying over and over to high-end content until you succeed), then currently your best options are probably MNK, SMN, BRD, NIN, or any tank or healer job. With that said, I think it's rather rare for people to actually get skipped-over for being any particular job, unless there's already someone with that job in the group. If you want to hedge your bets, SMN and SCH are tied to the same base class such that leveling one also levels the other simultaneously (even if you never actually use one of them).

With that said, if you're not going to try to be a top-tier raider, but just do the casual endgame stuff (i.e. anything you can complete via the duty finder and succeed with randos), then your job choice matters very little. Any of the duty finder content can be completed with any job setup.

Generally speaking, you should just go with the job you find most engaging. It looks like you've leveled most things to the mid-40s, so hopefully you got a feel for everything and have some preferences.
