return from the past

[Werhusky]

Welcome back
The swap from PC tp Playstation was also odd for me and I can imagine it to be even harder if you have a long term break inbetween
I'd recommend you to still try your white mage... it was your first choice in the game, it cannot be utterly wrong imo.
As for choosing a new class... well totally depends on you...
Casters have to struggle to cast while dodging AoE so do bard/mch past 50. Easiest there is kinda smn as you can DoT up then move but a proper level 60 rotation eats all my focus after about an hour. Blackmage puts easy high numbers but also has a harsh rotation on level 60. Bard/Mch are lower on DPS.
Melee have always to dodge mechanics meant for tank and AoE that are directly at boss. You will need to keep positionals to keep DPS up. I think all 3 have a fast rotation and some skills you have to use in the right moment. I only have MNK on 60 yet and I still put acceptable numbers with my derpy button mashing.
For healers... theres white mage you fear atm because you return... dont be shy its the most healy class in the game atm. Astro (unlocked only past 2.55 though) is pretty similiar, has a shield option and you will want to learn to weave the cards to help your team. Scholar is the most DPSy healer as you can leave the healing to your fairy but as SMN you want a good pet control to keep it up... will have even more skills than WHM in total.
Then tanking. You say you dont want it. I feared it myself and now its my second main... try it learn fail then decide

Hope you find a good way back into the game ^^
