I think there needs to be a spot just for wards. I don't really see why you have to give up an item late game, or just go wardless. I think there should be just a slot that can only be for wards(maybe oricles too). It's annoying when the team is like "buy wards [insert name]" and they're like "[insert name]: I dont have the inv space". I don't think this additional spot would change gameplay much.
Also i dont like how on proving grounds, you can only buy oricles extract if you can't go back to the store after you leave the base. Am i just supose to die every 4 mins to get another?
