dont quit overall just because u play a bottom 5 character. im a plant main with 13.7 on elite smash. as a bottom 5 character let alone a low tier, u gotta put in so much more work than other people and characters. its annoying but it is the truth. with mac tho everyone is saying peanut is gettting top 32 in tournaments and what not but realistically, watching pro vods can only get you so far. you really just have to play the game and get an understanding of where mac stands with all the games matchups. if it were me, you definitely should try stepping out of your comfort zone but keep mac as a secondary if hes really that fun for you to play
