You must have played a great spacing game. Because that what Deidara is made for I guess. Too bad Naruto isn't great as people think he is. While being a pretty good all around character he doesn't do well in any of them. He does have some pretty nea tricks, and take a lot of skills to play with him. He ain't a walk in the park like other characters. The same goes for PTS Naruto.
Also Deidara isn't a easy character to master. You gotta know how to space. If you can't space, then you're going to get put into the ground. He made for long range. So playing those type of characters are as easy like someone as TS Shik, TS Temari(overpowerd little monster), and Sasori. In the end, Deidara is like Seth from SF4. Where you need to wait for mistake, and play defense to win.
Exactly! Unless you're TOTALLY AWESOME with Diedara (I beat my opponent at less than half strength AND while I was less that and inch away from him after all.)
