No triforce Corki
A while ago I made a threat about Corki not having much synergy with triforce anymore and today I tried not building it on a game... I also had Deathfire touch as a keystone as opposed to thunderlord's and had only magic pen from masteries as well, increased damage from abilities as opposed to attack speed... here's how it went
I lost xD but somehow I got an S? I ended 20/9/19 I had a VERY good thresh by my side and during laning phase the enemy vayne probably cursed me and my ancestors over and over again
I built
+
first and luckily as soon as I got to lane I leveled up to lvl 6 and was using rockets and every skill without much contempt, that said, Corki doesn't seem too apt on charging Tear, at least not as much as Ezreal... either way I managed to rack some kills and built

I have to say that my damage while being somewhat high by that point, most of it came from outfoxing the enemy, getting them caught on the package trail was incredibly effective because it was doing crazy damage... for the first time I felt pretty confident jumping forward with it as opposed to sideways or backwards...
but my autoattacks were pretty lackluster, coming from building triforce on Corki you are so very used to chunk people from rocket + AAcrit but with this build my crits didn't feel particularly strong, as a matter of fact autoattacking didn't feel as useful, much less weaving skills, I kinda lived for the damage from the package trail alone until I hit level 16... this is where the fun really began with my ult at lvl 3 the big rocket was crazy, I chunked a vayne beyond half health with just 1, I also did 2/3 of a malzahar's health with Q+R alone...
Aside from autoattacks not being as good as a triforce build, I think that Corki's early ratios are too low to build around them and granted that he isn't particularly apt to stack tear as fast I think that this build isn't particularly effective either... also I find it so annoying that Valkirye has no AD ratio but the package does...
Next I'll try something like:
+
or maybe an early
? does anyone play Corki around here anymore?

Maybe not directly on Corki but if someone on your team has it... oh boy, the damage you'll be dealing increases even more!
