Taking in account it helps to balance a bit the match-ups issue, and make something to go at the offensive when all is lost on place of just rage quitting on mid-game, so, yes, it can balance a bit the misspredictions and other WIFOM and stuff issues (it also does help to give more variety in-battle). But of course, some people can get really mad with a critical-hit, and they are the less luck-needed thing of the metagame, so, a metagame without them is not really something bad, at least for that niche of people who rage with critical hits, I don't really care to play something like that, but I guess some people do, and it's not really something that game-changing nor important at all.
I guess the non-critical hit metagame just make the Stage 1 with 0% of rate, because that could be injust against the High-Critical Hit moves, Super Luck and stuff abilities.
I love Caterpie, he's a so adorable little bug! ♥ (Also, sorry for my English, I'm still learning it and I'm not a native speaker).
