Elemental Dragons: They are just as valuable for you as they are for the enemy team.
An example someone used, of which sieging buffs would benefit a lot, you would LOVE an water dragon. But what if you dont get it? Now theres a chance you wont get that buff at all for the rest of the game and its a huge blow to you, and your comp. While the buff may be better on your comp, is a blow to you if you don't get and it still benefits the other team.
At least thats what I think was the goals with these changes o-o.
