Tried many builds, and this is my current favourite. Prior to this patch, I used to play a 6g,6w,3b emblem build w/ a Focus Band, as building for mobility was more difficult. HP/MS are the most important stats imo, however, as their value is inversely correlated, you can just focus on one over the other (either go 6 white with a focus band, or go black with a glass cannon / utility setup instead). With the added range and damage increase this patch, it's much easier to build for mobility, so for now I'm prioritizing: Move Speed, CDR, HP/Sp.A (in that order). I prefer not to use Wise Glasses as I feel it's more of a JG item, You benefit the most from it after Lv.10, and when snowballing hard, but Espeon is more an Early-game 'mon, and flat stat increases work better early on. If using X.Atk for flipping, then Wise Glasses is probably a superior choice over something like Shell Bell. Using a Float Stone frees up your Battle Item Slot; the the mobility it provides enables you to take Eject instead of X.Spd (if desired). I prefer the instantaneity of Eject. You can run triple offensive items instead, but there's a sweet spot for damage output (e.g. I'd rather reach bushes to gank and escape death 5% more often, than KO enemies 1% more often. Espeon is rather good at securing though, so there's a valid case for the latter). ... https://www.youtube.com/watch?v=wKXQVkNTNUo
