OMG I've never seen a gordin like this before I like it a lot, although maybe even speed wave would be better(?) Also desperation with noontime could help keep him at 100% better than renewal.

gordin might have trouble staying at 100% HP to keep refreshing bolt's effect active even with Renewal. Either switch out moonbow for something like sol or noontime (aether isnt a bad option either but 5 turn cooldown is too long to wait and use the weapon effect again) or replace refreshing bolt.

other than that, the build is great.

Impressive Gordin, refreshing bolt is a nice weapon to have (especially in arena since every single point is necessary), other than that, you can use different weapons to see which one you prefer... overall is a powerful build and its nice to see ^^
