Nobody wants creep block to be a mechanic.
Just revert any changes you made coming into pre-season. csing has become a pain on any champion whose AA range puts me in line with my caster minions. Champions with larger models make me feel like I'm playing an arcade game. Small models get stuck for several seconds 50% of the time that they TP onto a minion.
Stop trying to make creep blocking a mechanic. It's a hindrance and a step backwards for the game as a whole. It's the sort of sh*t that should have only existed in the primitive, early iterations of LoL and should have long since been all but completely removed.
