I don't really have much to add but I did play WoW for some time, switched to FF14, played both for a while, and now am pretty exclusive to FF14.
I'll start by saying I prefer the race and lore WoW presents. This is -not- me saying I -hate- what FF14 has, I don't! But FF14's lore is not at all to the level of WoW. Granted, FF14 is a newer game, but what do we really know about the Keepers? They came over on ice and... that's about it. Roegadyn have an old language that's cool, we know the -names- of Seeker tribes... we get blurbs. Whereis, in WoW, you had vast background to draw on for races. (I RP, so this is very important to me, it helps me make a character.) Now, we do get answers in the lore forums and such, but lore is still a spotty thing at best. I believe one of the devs recently talked about how they don't focus on background lore because everyone is always looking to the cool things in the present and future that are happening.
For this reason, the races just tend to be very homogenized to me. Roegadyn are big humans. Lalafell are small humans. Elezen are elven humans. Au Ra are scaled humans. Etc.
HOWEVER.
FF14 just has the better community. Look, I've read the horror stories. I know what a lot of people think about us RPers. But people never spoke in a dungeon in WoW. You silently speed ran it and -that was it-. One mistake, even if you explained you were new? You were out - unless you were the tank, and then you could stand in ALL the AoEs, eat the instakill ones, and then ask why you died and point the finger at the healer. The RP community was even worse during my time. You couldn't just ignore people, you were forced to deal with nasty little cliques who would make your time -hell- if you RPed with the wrong person. I genuinely went through depressive episodes, BAD ones, during my time playing WoW. FF14 gave me hope. FF14 made me love playing MMOs again.
So, yeah. That's my opinion. Is FF14 a little weeby? Ehn... it's art style is definitely anime, but FF always has had an anime style. (Yes, I know anime technically isn't a style, but everyone gets what you mean when you use it that way, so begone pedants.) Either way, it's just preference - the people who won't give it a try are missing out on a fairly great experience, no matter how you want to play.
