Is this build wrong in Corki? Toplaner Fire Corki

I laugh because they say my build is troll (and I play him in the top lane):

Keystone: Deathfire + 7% magic pen

**Runes: ** 10 AD 10 Magic Pen 8 AD at level 18 3 armor 4 magic resist

Items: and , , or depending on my needs.

Regular damage per game: over 60K I did a cuadra last game... almost Penta (freaking Rammus stole my Penta)

It is sweet when they die cause of the Deathfire too (due to the high AD ratios it has).

I max E because it procs Deathfire 4 times per second (one of the reasons Deathfire deals damage twice a second is to avoid it dealing damage multiple times each second, I abuse it with Corki's E which deals damage 4 times each second and Corruption Pot) , causing it to deal way more damage and reducing resistances, also it is a hell for toplaners (because I can time them and use W)

Tip: when you get the package dont be scared, dive on the enemy team and get them caught on the fire, with magic pen, deathfire and Liandry it deals way too much damage.
