I like their idea for dragon. If you want gold advantage, you push towers. If you want to build up your teamfighting strength with bonus stats, you take dragons, plural. This limits the huge spike that tends to occur in most games currently, where, in a roughly even game, if one team can take tower + couple of kills + dragon, they zoom out to a large lead in all respects of the game (even top lane will probably be titled from the gold injection). But it also says to the team that falls behind that they have to continue to contest subsequent dragons or they will fall very far behind (rather than saying, "Hey, we're behind, but we got Ziggs and Tristana, let's just farm till 40 mins and give up everything except Baron and our base towers."
