Consider this before you demande rageblade nerfs
Go look some time at which champs are doing best now at top lane. Those would be the mega tanks, rageblade users, Graves, and Yasuo and Tryndamere. The last two are going to be tame once Warlord's Bloodlust gets hotfxed later this week, so what happens if rageblade gets nerfed? It's worth keeping in mind that rageblade users haven't even got particularly abusive win rates with the item in its current state.
Triforce got nerfed for fighters, mastery changes turned the meta against Riven and Fiora. If rageblade too gets nerfed too hard, we're gonna be right back to early S4 top lane meta, where you were either Renekton, could survive Renekton, or died to Renekton.
