Thank you guys for the input! It's helped me quite a bit!

EDIT: I added in a 2nd build, to make Rumble a bit "tankier", I'm not 100% done yet, but I'm getting close!

Ok wouldnt a tanky Rumble better i mean...CC boots Force of the nature if heave dps team thornmail rylays staff and etc...wouldnt it better ?!

I do like the AP, but think you need more health. I tank about 1000 more life, and get way more kills. But just as well, i tried this build, and it does work. I guess im more of an agressive player, and need a little more health to push the battle and carry with rumble. Getting 2 recent consecutive games with 27 kills.
+1

I like it If your focusing AP not sure about your rune choice and you need to find one more skill but this is a good guide for any rumble begginers

Thanks for the review ^^ I'll get right on that later today.
EDIT: added a few chapters for indepth laning and actually playing in mid with Rumble.

EDIT: I want to know the thoughts and comments people have on this build, so please post!

Well i like you build but you should explain your item choises or optional items, explain why you max First flamesplitter secont electro-harpoon make it just a bit more detailed and and i am sure you'll get many good ratings..Give more details like what you do in early game-mid-Late game so people take an idea How to play him.+1 from me and hope you Take in consider my Tips ^^

Just to point out that I just started this account, and don't really know all of the fancy things I can do with this yet. Also, my item build is not yet finished, because I cannot seem to get far enough in the game to consider what items to get! They always end before I can finish anything that far.

I'll post pictures and etc. later.
