This is my first thread here so i'd like to say thnx for a great game!
Now, onto business. Im an avid DotA player, as such there are some things LoL doesn't have that annoys me.
Mainly, the inability to store/drop items. I'm talking about , say, an item that requires 3 item slots to make. But you already have 4 items hogging your slots! The only way to get this item which requires 3 items is to either sell or upgrade another item to make room. In most cases i have to sell - only to buy the item again and losing hard-earned gold.
I think something should be added to fix this issue. I propose a vault like unit - like the circle of power from DotA - that can hold and make items and store them for you until you get back to base to sort them out. This would up my rating of the game from 95/100 to 97/100!
