youve been playing prof for a year, thats why when i went fox, i took a stock of you only using shines, you mightve expected it, but you didnt really do anything about it.. ICs arnt even hard to use, you really only need wavedash to D smash, Wavedash OOS => grab, and learn a few chaingrabs , spamming B whn theyre at a distance, use a finishing move whne their at high percentage and hey, you have an ICs that can get 9th place at a monthly. Most of the time, id say its the match-up problem, people dont play ICs on a regular basis and arnt used to it.
and if you tell me to learn it? tbh id rather spend that time to improve my matchups against real characters.
Ive only been playing competetively for just over a year, and with ATs for 2 years. Its not really that long compared to how active the scene was back then.
