For yasuo, Tempest. Wandering, and Windwalker (these are the only three that matter but if you want another one take Horizon)
Jinx: Arsenal, Comet, Plan A, Antsy, Eager along with
rush is pretty fun imo.
I don't know whats best for her with 3 aug yet but it will feel bad losing infinite flash to keep the damage augments.
Ziggs is pretty diverse.
Healing Ziggs: Delayed, Shatter, Hexhealing, Leftovers, and Mayhem= better healer than sona with more CC.
Mage: Shatter, Fallout, Overkill, Brink, and last one is whatever you want.
The ult augments are pretty important for mage Ziggs so he can clear mobs fast. Rush
again % hp damage is too important to not get.
Auto attack DPS: Bounce, Shorter, Brink, Distributor, and Overkill.
Only reason for overkill is so you can gain 80% damage reduction when you're in a tight spot, otherwise your main damage is your autos and you want to spam q when your passive is on cooldown to instantly refresh it.
Rush
for it's % damage obviously.
Sona: Cadence, Cascade, Hyped, Benediction, and flurry.
I haven't tried it yet but having her ult back really fast sounds good to me, and flurry is nice when your yasuo doesn't have windwall ready (or you just lack one on the team) for the Shadow Kayn Ora Phase. But if you want to lag the hell out of your teammates replace flurry with Concerto.[sg-miss-fortune]
