The Dragon Buff, its cool, but gives hardly any room for comebacks.
The reason why buffing dragons reduces comeback chances is because of the minion push and those who are losing have to fight off minions and winners get free dragons. The buff on the dragons reduce the chance of a comeback. There's less chance of coming back now then there was. The dragon bonuses make it easier to own the jg and just camp right outside of some towers.
Also supports got a nerf so the better jg certainly wins the game.
Not sure why the gold coin is gone for supports. Just had a yummi support and the current items don't help the cat at all. There isn't an viable gold option for the disney cat.
