Baron Buff is too strong!
When you are losing but still have inhibitor turrets and the enemy gets baron buff, you are going to lose every last inhibitor. God forbid you're already lost an inhibitor or two cause more often than not the game is over. Towers are already melted to all hell, add a baron buff and they pretty much don't exist, and the stat boosts just throws it over the edge. I can't tell you how many even game I've seen decided by whichever team got Baron buff first.
