If I were to go anyone other than Marth it would hurt my tournament placings.
Ive spent so much time with Marth, I feel I should be able to adapt to anyone i fight. Obviously unless im getting first, im not properly adapting.
Top player such as hbox, colbol, jman, hax etc etc. dont change because i would assume they feel the same way. But you know what they say about assuming.
I feel low and mid level players change characters because they do not know how to work out strenghts and weaknesses of a match up, so they resort to switching up setups all together.
with that said IF I WERE TO GO ANYONE ELSE, i would use sheik.
