Nem, what makes you think FF14's is too hostile? I think they should be way more hostile. There are so many bad players who have no idea what they're doing and don't even bother to ask others for help. I can't tell you how many times primals fights have started while I was casting Protect. -_-
That said, TERA is also an excellent pick. Best gameplay of any MMO I've ever tried. An absolute delight to play.
