I sorta agree with juggernaut, but I on the other hand label and accept cheap disadvantages in a match. If you feel that a bundle of the characters in the roster is cheap, go the opposite direction and use characters with disadvantages that even
worsen your chances.
I know this sounds reckless and stupid but I'll explain
I ran most fighting games with characters that were said to be very bad when evaluated by exceptional players. I used gen in sf4 series and had a very hard time with coping with my win ratio, but once I finally took up on other characters, learning and using them exceptionally was an easier process. I improve through steps, from bottom to top. Its not like I search for the worser character to prove an amount of skill I possess amongst other players, I actually do this to challenge myself.
(It has to be a character you would struggle using, avoid characters you are likely going to have it easy with.)
Believe me, I only want to help. Make things possible for the worst characters... combos, tactics ect. Just keep it up you will not regret the deeper value your losses have granted you, peace.
