Dragon Damage and Defense Needs buffing
The changes to dragon has officially made it the #1 objective early game. 8% dmg increase is OP no matter which way you look at it. Not to mention that some champions can solo it at VERY low levels. The first buff needs to be nerfed down to 4% or something more manageable. Otherwise the advantage it gives, ESPECIALLY to fed or snowbally champions is massive. Imagine a fed akali/fizz with free damage because someone like pantheon, nunu, or warwick solo'd dragon at lvl 3.
So including a buff to early game dmg and defense in dragon, I believe that to champions that already have the buff, dragon deals increased dmg, and takes reduced dmg. It would stack with each buff they have. This would prevent solo'ing the dragon for free stats and whatnot.
Another idea that presented itself was that if you kill someone who has the buff, you gain the same buff but for a TEMPORARY time. I'm not really sure about this, but my friend thought it up, and i just put it here.
I feel that the main buff that dragon should give is the final buff. The would be the one buff that I would completely understand being a gamechanger. However, because that first dragon buff is so overwhelming, you can pretty much negate the other team from getting dragon if played right.
TL;DR.. Dragon buff is too strong, and dragon itself is too weak. It should get stronger and stronger as the game goes on in accordance with the strong buffs it gives that are permanent. Pretty much the buff needs counterplay.
