The problem here is that everybody is focus now in early-mid game, the shorter the game, the better. They want the best stats as fast as possibe (there's the why a few use per-level runes).

You don't take life-steal because you need more damage in the shortest time as possible, cause you don't need life-steal after an ace (unless you are aganist karthus or kog'maw but banshee give you more against them).

The attack speed is nice, but usually attack speed user go for fevor or the "infamous" thunderlord instead. (yeah, I hate it)

I think if they change the how thunderlord procs, everyone will take seriously the other keystone.
