Don't want this to turn into TERA vs Swtor thread but here's my 5 cents;
Tera is just another Korean grind mmorpg ( Like Aion for example ). Ppl are disposed towards saying: 'This game will be the next WoW killer & That game is the future of mmo gaming', etc
Sadly, most of the insinuations like that are pure rubbish; I played around 7 mmos so far and it's the same story with every upcoming title. In 3-4 months TERA will be mostly forgotten, the fate most of the new mmos share last few years.
Today's mmo gamers are more fickle and prone to changing games, etc. In reality that won't change the situation of 'mmo crisis' (so to speak) we have today....
