I found how to dominate with Pyke and I'm not telling.....
..... I will give some hints though:
Change up your rune trees (Neither of the two trees currently being meta'd are correct; I've played over 80 games on those runes, and they don't even compete with my new runes...)
Attack speed isn't a bad thing.
Movement speed is more important than tankiness or AD.
My Last 4 games:
17/2/5 11/3/13 21/1/9 16/1/11
And all of them had extreme Pyke counters.
Last game actually had 3 3 man sequential R chains.... (not right after each other either.... kills were 15-17 seconds apart, and about an entire screen away from previous kill).
Most of these are Pure Pyke kills... solo or mostly my own damage.
sixth item varies (if you even get that far, if we're being honest) in whatever order suits the game
