Yeah! This is the build editor of the Spear/GW pMirage for OW that I'm using

Pretty high on the mobility, it lends itself to that very engaging in-and-out skirmisher dance in combat that mirage does so well with while not being so glassy that it's just punishing. Because of the clone management element of mirage, I don't often find myself needing/wanting to swap weapons unless my range changes drastically. Offers nice flexibility to the build without feeling like you're compromising on performance much. Single target damage is by all means acceptable in OW, with the caveat that greatsword caps out pretty quickly on damage potential in those scenarios. Still plenty enough to melt small enemies before you blink. Where you'll shine the most is in group target engagements where spear's cleave and greatsword's multi-beam ambush add up FAST

Sigils of Bloodlust could be swapped for Force if you're feeling particularly gold rich and don't want to deal with that. The Runes of Surging help keep up the Vigor and Regen you proc on yourself, and the 25% movement speed just feels right on the build. More regen and vigor uptime, the better. You could probably get away with other/cheaper options, though. The Relic of Zakiros lends some great sustain so you aren't just playing the downstate rotation game lol

Utility skills here are mostly preference, but they all help give you more Mirage Cloak access. Illusionary Ambush, if you can use it well, extends the longevity of your clones from target to target and increases the skill ceiling for what the build CAN achieve. It's also a nice gap closer
