When you Ace the Enemy Team and Take Inhib
Go for Baron AND THEN Dragon... 4th Dragon < Baron and 4th Dragon. You can end with just the pushing power of Baron, why wait for the small chance they are going to let you get 5th Dragon in a game where its pretty much tied and they out-scale you?
So idc if you want to send one person to solo Dragon, but take Baron please its a free uncontested Baron... 4th Dragon and the chance at 5th Dragon is not better...
