Boot Enchantments...no thanks
I know ill be downvoted for just the title alone but the thing is, boots are already strong enough. I don't know if everyone in this game realizes how extremely powerful movement in itself is. The sole thing that made Kalista strong back when she actually did things was kiting and her speed. They didn't want Cass to have boots and because of that they needed to make her passive be movespeed because she would be so freaking underpowered without boots/passive movespeed. Just a few examples i just think taking boot enchantments out was a good balancing option.
Bloodrazor
Cinderhulk
Runic echos
Warrior
