Can we semi-revert Runaan's?
Remove 10% critical strike chance, add 20% attack speed? It feels horrendous on it's own. Crit users are also complaining about wasting 20% critical strike chance so removing some crit chance in favor of attack speed could be good for Runaan's users anyways. Gold wise this would be about equal(actually 100 gold less in actual gold worth but I think the 20% attack speed would be worth it. Item would then be:
60% attack speed, 20% crit chance, 7% move speed.
's
synergy nerf as well.
and 
build path, but she'd live.
on
and that alone giving all the slowing power I need from the crits. It makes me spend far less thought on how to counterbuild.
