Towers and losing lanes
I was thinking of and idea that includes having gold for your own towers. The gold would be separate from your own pocket cash in game and be the towers own little gold stash. The tower can only get gold when an allied champion is around a friendly tower and when it kills a minion, not a champion. The gold it acquires can be used to upgrade it's damage, health, armor, etc. This would help out losing lanes by allowing their tower to be a lot stronger and having something they can actually fall back to and rely on. Late game champions, Vayne for example, can get stomped out early making her power spike come a lot later. This would also make to where if you don't have a good jungler that ganks consistently, the losing lane won't get pushed as hard. This was just a random thought I had and thought it would be cool to add in the game permanently or just combine it with the bilgewater brawl gamemode.
