Same here, I would only vote for 2b and 2c
Glyphing is the only skill besides muting that doesn't have anything you need to counter and it also has a pretty long timer so it's almost impossible to not click in time unless you're really multitasking or lagging
If you remove too many of the ???s and insta fails, it's gonna be the easiest skill in the game. I know insta failing from a misclick is super annoying and I've done it when I was going too fast, but technically you're not allowed to have a misclick and it's not like you fail every single misclick you do, it's still relatively rare
2b and 2c seem the most reasonable to me, if you remove the insta fails when doing much lower glyphs than your rank but still keep the ???, you should technically never fail, because it should only take you a few clicks to get the whole glyph done, but still keep the theoretical possibility of failing
2c should be good enough for glyphing at your current levels, if you remove the insta fails after a ??? you'll only be able to insta fail after a misclick, maybe even lower that chance a lil bit, but not completely remove it
