I agree. I would add that they are all young and naïve. Tyler probably let all this newfound attention go to his head (comments like those found on this site don't help; "He should go drop that metalcore crap and go solo!") and felt he could "do something more than just be in a metalcore band." He's probably realizing that solo work puts a lot of pressure on one person and perhaps misses the intensity of being a part of a full band. Again he's like 20 so he's probably unsure of a lot.
Completely agree. Hell, I'm just about 20 and I'm unsure about a huge portion of my life right now haha.
Didn't know that, is there a source somewhere on that?
