Hey there guys, I'm Simon and I'm "CodeBar" on the Vietnamese Garena Servers. I'm currently in Diamond 1 with 50lp, however it should be said that Vietnamese Servers are easier than EU or NA for example.

Pros:
Bully's most if not all champions in lane
Sustain during lane
Massive unmatched poke during laning phase
Lots of Crowd Control
Constantly pushing the enemy to their turret

Cons:
Requires Quick Mathematics to keep spells within the Danger Zone
Silences himself when overheating
Bad auto attack animation, so hard to CS with

At the start of the game you should play safe and only poke with your Q till you have all 3 abilities, even with two abilities even you can go balls deep.
Always keep the river or tribush (depending on which side you're on) warded since you'll be constantly pushing the wave to the enemies turret.
When the opponent is last hitting creeps under turret, harass them from outside of turret range with your E and Q, and once you get to close and the turret targets you because you dealt damage with your Q, just turn on W and walk back (this is key to controlling your lane, don't let then free farm beneath their turret.
THE MOST IMPORTANT THING IS, since there was a new update, the Danger Zone (when you go between 50-100 heat) got a massive buff so whenever possible keep atleast the Q within the danger zone( so if you had 10 heat for example use your W and E so you get to 50 then use the Q so it deals 50% extra damage)

This is where Rumble excels. During team fights the worst possible thing is to overheat before you've cast your Ulti, So as soon as the team fight erupts use your ulti since there isn't any buff gained if it's cast in the Danger Zone, and then follow up with your spells

Positioning Your Ult

There are two different type of ulti's the offensive and defensive.
Offensive - Personally, I prefer the offensive ultimate, if you're fed and have a decent amount of AP you can place your ultimate on their backline applying the 25% slow as well as the Rylai's slow, making it simple to use your W then Q and E ignite to 1 hit their AP or preferably AD carry (AD's seem easier to kill since they have less Crowd Control than a Mid champion)
Defensive - If your backline (AP and AD Carry) are fed and carrying the team, place your ultimate so that their Bruisers have to walk through your ultimate to reach the carries buying them time for the spells to come back or to simply kite.

Note: The absolute perfect heat to be at is 55. Since once you're at 55 you can cast all of your spells within the Danger Zone making you one crazy killing machine.

Never. Rumble is the best team fight champion out there, you need to be within range to ult if a fight breaks out. As well as that you don't have the best damage to take out turrets, you should leave it for another champion.

Balls was the player which got me into Rumble and this play will just show how Rumble is one Over Powered **********er. Remember Rumble is one ballsy **********er. Play Video
