I mained Rachel and Noel before picking Ragna.
I go to monthly Smash tournaments, and at the venue's arcade, I noticed there was a BlazBlue cabinet. I watched the intro and thought it looked pretty cool, so I played it. Rachel was the first character I picked up on random, so I just kept playing her. After a while, I began to realize I'm not really a projectile player, so I went to Noel, who some people told me was a more direct character. I mained her for a few months, practicing basic combos, then I slowly began to fail at them... I lost almost every match I played because I couldn't pull them off anymore, so I went and picked whoever told me was the easiest, most direct character in the game. I noticed I could actually hit people with his Astrals... AND THE MOST NOOBISH RAGNA MAIN WAS BORN YEAH
I love it how my main progression is increasingly downwards in skill...
