This isnt a very good example of what tera is REALLY like. Most other trailers (gameplay) ive seen show the game off a lot better. If you want to see the real tera i suggest you visit the official website.
I agree, terribly generic and the graphics remind me of final fantasy XI but improved. I hope it turns out to be not terribly generic and i hope it becomes my FFXI-2 (sad I thought I would've found that with FFXIV)
