Put death timer reduction on third or fourth dragon buff.
Riot stated that they don't like how dragon and herald are taking a back seat to turrets when team fights are won. Meanwhile the players have been complaining about the outrageous death timers. So put a death timer reduction on dragon and watch it suddenly become the most contested objective in the game. It's completely reasonable to get to 3rd dragon by 20-25 minutes and would reward the better team with a nice 10-20% death timer reduction. If the team that secured 3 dragons lost the one fight at 30 minutes that can often end the game for the otherwise winning team, the reductions in death timers would make it so "losing" team couldn't come back as easily after picking one or two champions off during mid game.
