Could I get some help with Gunner affixes?

So heres what Im after, I need a decent set of affixes if possible a step by step would be great for my units, I want some decent damage and survivability, Im using Gu/Fi build as well as Gu/Hu, I have 5 slot Ray units, so thats what I have to work with. Any help would be great, thank you!

Basically you wanna go for Damage>HP/DEF>PP

Hard to tell you what to go for, as I don't know what you have. PP you don't really need because of Showtime, Def depends due on how you play. I abuse the iframes very well, so I just focus on HP>Def, But this doesn't mean it should be ignored.
