just give garen more spins for building attack speed.
would solve two problems of his.
1.) crit items would stay good on him after the rework, even when he cant avoid getting crit without attack speed
2.) attack speed items like 
become more efficient, and he remains a threat even with his spin on cooldown
edit.: 3) precision would become a more viable primary (or seconday) rune path as an alternative to resolve (sorcery), with less wasted stats.
behold my amazing paint skills.
riot recently said that one of their set goals is to add additional build options and ratios to champion kits. obviously, adding AP scalings to garen doesnt make much sense in light of his lore. but adding additional spins for building bonus attack speed would make a lot of sense considering the already existing crit scaling on his abilities.
