Renekton mains?

Generally, if it's a hard melee matchup, I start W. It's extremely rare, though, pretty much only VS Tryndamere.

Q is a much better start against the vast majority of enemies, mainly because of it's range, but also because you can hit the minions and heal with it.

I also almost always take E second for harass maneuvers, unless, again, it's a hard melee matchup. Against Riven or Garen or Irelia, I'd take W second. Against someone like Darius, though, take E so you can juke his Q, or take E against Illaoi to avoid tentacles, or in ranged matchups to close the distance, or in other cases to avoid skillshots.

Basically, if you're gonna be in an extended melee trade at lvl 2, besides VS Darius, take W second.
