I could NOT agree MORE!
I get very annoyed when people have defeatist attitudes. I'm not a Krool main, but I am a Ridley main, and he has had his fair share of moaners too, where I'm internally thinking "Just go away and main a high tier already."
In my personal opinion, this games balance isn't even that bad, especially compared to previous games.
It's so easy to try and blame your character for your losses, rather than check your own play, because you can then justify not being inferior in play to your opponent. I've just started going to weeklies, and have been to 3 now. I have gotten royally destroyed by players at my weekly, many of whom are playing very high tier characters. I went 0-2 my first week. Did I blame Ridley? No, I did not. The people I ran into were vastly more knowledgeable and vastly more skilled than I, and they were performing the game's fundamental mechanics to a much higher and more consistent degree. Admitting to this is a very important part of improving your own game, whereas just condemning your character for your struggles will only induce saltiness and make you a worse player.
I've fought a Pichu main every week in friendlies, spending sometimes entire stocks being electrocuted to death and stage-spiked. Did I blame Ridley? No. I'm not good about DI'ing his combos or knockback effects properly, and am not playing a solid neutral game. He is beating me. He is not beating Ridley, but me. So what? Learn from it and get better.
Guess what? Last week I beat a Pichu player in bracket, as Ridley. I also beat an Inkling, in a bracketed match, as Ridley.
Blaming your character for your losses is a very good way to become extremely toxic towards the game and that's when you stop having fun.
Ya'll need to check the attitudes and learn to play, learn to lose graciously and learn from it, and stop complaining all the time about King Krool's tier placement. After all, if you stop blaming your character and start actually trying to learn matchups, learn what you can do, and practice instead of complain, you may start beating some folks and Krool may surprise you.
