Inadverent Nerf to Quinn??
Most games now finish around 20-30 minutes. Changing homeguard to 20 min is literally taking Quinn advantage away for 80% of game..
Suggestion: Give us the option to purchase Homeguard early if need b but everyone will get it for free at 20 min mark. If you purchased Homeguard then at 20 min it should be default boots while your allowed to choose other enchantment. Whether you refund the amount purchased is up to you riot but that is my suggestion.

to compensate in the early game.
Still I feel her ult isn't healthy for her, specially with Homeguard, everytime you fall bellow 75% of HP you just go B and run to other point in the map.
