I got 5k hours in WoW up to Cataclysm and 10k+ how in FFXIV (beta tester from 1.0). I think the story telling of WoW up to WoTLK, was told amazingly well and it had a strong point, but BC was even better. Things rapidly declined from Cataclysm and this is why I never got back, whereas I've stuck with FFXIV for 13 years.
