its very rare games even go so far that you have all slots filled, unless ur buying cheap items like spirit visage and wriggles. even then, you should sell those items for more expensive ones when all your slots are filled.

AFTER that, if the game still goes on, the support should hopefully still have at least one slot free. if the game goes longer than that...by this point gold will no longer matter, everyone will have several thousand gold and no slots to buy items, so you can sell one item, buy wards, place them, buy the item back.

this is a problem as you will waste time recalling and you are handicapped one item if you run into an enemy or a teamfight starts. so maybe if the game detects that everyone has all slots filled with items that don't build into other items (a completed build), then it adds an extra slot to buy wards in.

anyway this happens in less than 1/500 games, so there isnt really a reason to add a feature like that
