this is my hybrid rumble guide. i made alot of changes since this guide first came out and hopefully its better than it was. rumble is a bully in lane and has good early game harrass and i play him whenever i have the chance. :)

Cons

item dependant
ultimate dosent do much damage
very ability reliable

Pros

good pusher
great in team fights
bully in lane

main:

promote: promote (in my eyes) is the best summoner spell for laning it helps with that extra gold and to push towers.

ignite: helps to pick off low health enemies and enemies that are getting away

instead of promote:

heal: is useful for teamfights and when you get low.

flash: a good initiating/escaping mechanism

Instead of ignite:

exhaust: helps in chases/focusing and can also be used in getting away

surge: useful for pushing and when in overheat also good when trying to kill people 1v1

NEVER TAKE THESE:

revive: worst summoner spell i know doesnt have any benefit really apart from getting back to lane quicker.

clairvoyane: dosent help rumble in anyway at all and only useful for junglers and supports.

Marks: the marks are for magic pen basically so you can do more damage with your spells

Seals: for early game tank

Glyphs: for early game tank

Quints: that extra health helps out early game makes you more survivable

hope you like this build... plz tell me how i can improve and rate :)
P.S dont look at the cheat sheet apparently they dont add up corrctly
