Proposition: Instead of deleting items, how about giving the option to ban it.
Ban the items that don't want to be used in a game maybe 1 or 2 items on each side. Plus item banning would be at the end after everyone picked their champion or at the beginning after champion bans.
For example when DFG got deleted because of certain champions that benefited from this than others.
Excluding the bans of jungle items, Wards, tickets, support items, tier 1-2 boots. There's probably more things that shouldn't be banned but I hope you get the gist of it.
Thoughts? Changes? New ideas?
EDIT: Only banned Full items
