"We want to reduce snowballing potential" - Riot season 4
We're going to give Dragon a stacking, permenant buff to anyone who kills it as well as make first blood more rewarding. We're also going to give a free dragon ward to the lane that can push their lane faster and help the jungler kill the scuttle crab. This will mean that lanes have to make "strategic decisions" about how they want to approach these new objective! (Oh and Sword of the Occult and Mejai's both come with stacks on purchase. Happy hunting!)
Seriously, I think it's kind of funny they threw out all of their work towards making early snowballing less of a thing with this new season. The dragon buffs are absurd and securing even one early means you're good to go for the rest of the game. A fizz with t1 boots and lich bane should NEVER have almost 400 movement speed. The global gold was chump change compared to the value this new dragon gives.
