Why are you saying I am trolling? This doesn't even make sense. This is a valid concern. I am a real player. My money is the same as yours.
Because as a real player you undoubtedly realized the reason and advantage of the Tera system right away! As a longtime WoW player I was indeed first taken by surprise when I started playing Tera towards the end of the Closed Beta. As an altaholic I always click my talents because it is too hard to learn key presses for 50 different character rotations.
But then I realized that Tera's new combat system was really fun! And the only way that could possibly work was without depending on mouse clicking. So I limited myself to 3 alts and found that I was enjoying myself completely.
So I'm not believing for a second that you really want them to go back to the old style combat system!
