The crit chance runes are there to fill the 5% gap needed to reach 100% crit /w Shiv and IE. A moment after writing this post, I've swapped the scaling MR for flat MR too (I've decided that, given Yasuo's rather poor start, getting a reasonable amount of mr from runes post-9 is a little bit too late for him to actually benefit from the bonus), so that's no longer a problem.

I've ultimately settled on two separate rune pages, one focusing on crit damage and the missing 5% chance + MR, and the other one, attack speed, penetration and a little resist-oriented. Already tried the first one in few matches, and it seems to work very well with his usual core. The second one is still untested, and since the PBE server is down at the moment, I won't be doing that too soon (either way, if the AS page proves to be more effective overall, I guess I might just permanently stick to that, although I have a feeling that it will not be the case).
