Here are my thoughts on this thread:
Some Frc's are hard (hcl 6frc6 air dash and ice spike come to mind) some are easy modo (sol's gunflame, tatami, and millia H disc and hair car) but the bottom line is that they are in the game and you have to learn them to play competitively. if you want to play CPU all day with no frc, no strategy, fine, have fun, but if you wanna win a tourney, have even more fun with the game and challenge yourself, then you need to learn it....I mean, you've seen them done in combo vid and actual matches before, what makes you think you can't do it too? just practice, there is no such thing as "too hard" only stuff thats literally impossible(like stuff made with programable stick in combo vids) for human hands and even then thats an iffy because how do you know out of all the population on earth that some human wouldn't be able to do it?...
bottom line is they all require practice and effort and experience to become second nature, even the easiest ones...so learn them if you like the game and want to play seriously and expand your knowledge and win and dont if you wanna play CPU and scrub friends and have fun that way....
