Hey i am fairly new to playing ranked, and i tend to play a jungler, in my last match, i had already had 4 successful ganks, and top lane was easily won. After a double kill Bot lane i call for us to do dragon, it was stole and we got tripled, we started with highish hp (75% all) and even if i had not messed up flash it would not have been worth it. This lead to us been snowballed against as cassiopia got the triple(and are not very good mid had been killed twice already, even though i really helped her early game forcing cassio back twice).
So my question is, is dragon ever really worth it before the point where the ad can chuck it in a few seconds? The gold is nice and all but after that game i just dont understand out side of a arranged 5`s why you would even try dragon.
