Honestly, I'd say find some people to enjoy the game play with. From what I read, it seems like you've been trying to solo through everything and only interact when necessary with others. I talk near daily on skype with my FC mates (granted, we also all know each other), but the difference in how much I like this game after I started playing with others was substantial.

But I think part of the issue may have been that you came in here with so many expectations from your knowledge of WoW. Not to mention, it seems like you went from high and mighty tank in WoW to... well... the starter glad can be a bit squishy. Not to mention, this game does not keep to a conventional tank. It focusing on every class becoming more dps focused to prevent boredom from setting in as much. Good and bad in some instances pending what your preferences are. I for one liked being a brick wall in other MMO's with tanks. I understand that trade offs must be made so nothing is OP, but FFXIV kinda makes everything more even.
