By all means you should play your main characters . Biggest part to improving is to be even more flexible , take pro players for an example . They can play any role at Grandmaster ranks . It will make you think more about decisions in game and you ' ll have a more developed game sense since you can understand the match game from more viewpoints . In the end we ' re all trying to improve to the next level Having more game knowledge and game sense will only speed that process up more more . I wish you good luck in season 3 ! Competetive game modes can be very frustrating at times , I ' d lie if I said I never rage etc . Just continue to remind yourself that you ' re playing to improve most important of all . Have fun while playing improving !
