Casual player looking for a company

I started FFXIV again after a loong break and am looking for a casual FC to do dungeons and raid later on.
I've main healed in nearly all other MMORPG, but am now dabbling in tanking, I can change to heals if that is required.

Ideal for me would be to have 1-2 dungeon/raid evenings a week + other adhoc stuff in between.
I am half a century old, so I really can't be assed to take computer games seriously, but I do commit to activities in relaxed atmosphere (have gotten my fill of serious raiding and emoraging about loot).
