Returning player - New Character

Good Morning! :o

I am a returning player starting a new character on Omega EU. I will be playing very casually due to work and other such commitments so am seeking advice.

I played ARR on PS3 and got to 50 DRG with all the DRG gear and various other classes and levels under this. I unfortunately missed the transfer window as I have only just got a PS4 and the want to really get back into the world; I certainly missed it!

As I'm PS4 I feel like everything I do is clunky, I've tried my best to look at some console set ups including HUD layout and the use of different bars for attack stance. I'm PUG so any PS4 player tips here will be very much appreciated.

Really what I want to know is if I should stick with the story with my first chosen class, or get to 30 for my choco helper and then start another class that may interest me, but therefore leaving the story until I am at the level needed again.

I'm only managing to sink a few hours here and there so it's difficult to prioritise as there is just so much to do! it's daunting but also exciting. Wish I was still at Uni where I could sink 30 hours a day in :p

Sorry for the essay!
