I bought him and I didn't do so well in my first 2 or 3 games, but after that I just roflstomped people who ever dared come near me, it's like the learning curve for Rumble is hard and I still think I have a tad bit more to learn about him but he just seems so nice to play once you pick up how to play him. I honestly find that when I first learned Anivia it has helped me with characters that have similar difficulty in the future but Rumble was something different.
Anyways what are your opinions of him?
