there are a few Sonya players who are very accomplished.
RIU48 has accomplished the most with her to date. Just watching his matches dont tell you how good he really is. You have to play him to realize all that he does.
Showtime just went to Sonya a few months ago and is already a monster with her. MLG Raleigh is when he went from being good to GREAT. Now there is no doubt that he is an elite. Currently RIU48 is the best Sonya, you cannot overlook his overall accomplishments with her, but Showtime is BARELY behind as #2.
Death retired, but before then he was a consistent top placer in major tournaments. He came back, and is in great form.
Clint da Beast is a great fg player who could probably play any character and have success, no surprise that he does so here.
Blake is a great Sonya, but doesnt travel much hence lacks CRUCIAL exp which is what hurts him in certain MU's.
