Should there be an item cap in lol? gosh that 10k unspended are annoying

Sometimes when i play really long games i can get to about 10k spare and full build, which is annoying because you see yourself slowly falling even if you're ahead. By doing cheap builds you can be easily countered by your enemies more expensive builds later on, even though you have that 10k...

As an option all i can do is switch the build situationally. but many times i feel that already have the right build and keep the rest of the game only buying consumables.

My suggestion is that there could be more than 6 items on your bag, so that you can fully use the gold you have and not get capped. As a way to compensate, the incremention of the 7th(or 8th) item slot should be made through the payment of a large amount of gold( in my opinion, a large 2-3k or more), so that not everybody would get it unless they really have the full build and a lot to spare, and because it is a great advantage, of course.

I think this would be a way to bring even more options for late game and to basically not get gold thrown to waste. :)
