Not so. The X shouldn't be as good as the T-70 or E, but a cheaper price can make it more viable. A headhunter is almost always worse than an A-Wing but it's fewer points. I don't want the X to be as good as the T70, but I'd like to not feel better off with Bs, which are in the same price range and have better survivabily, reposition, and aresenals...
My point was that the X-wing needed either 7 points of extra power at its current level, or a point reduction of seven (maybe 5) points in order to make it the equal of the T-70 in competitive play.
As for competitve play, say I buy two X-wings and you by a Punishing One. Guess who's winning nearly every game? Or say I buy an X-wing and you buy any other expansion . Guess who got the most bang for their buck?
