Mods

Hi, I’m wondering if I can get some mod help? I’m working on mods for GAS, and I found a diamond mod, which I’m considering putting on him and slicing. But I’m just trying to understand the secondaries more, and if these are good. The speed secondary seems good to me, but I feel like the others are low, and I’m not sure if that’s normal or if it’s just chance that the other secondaries don’t seem as good. Ultimately, I’m looking to understand more about how secondaries work, as well as if this mod is worth putting on GAS and ultimately taking to 6 dots.

Offense type, diamond mod. Level 15, tier A (I got it at that tier, I did not slice it.) Secondaries: 

(2) 625 health

(4) 17 speed

(1) 0.54% offense

(1) 5 defense

I know offense and speed are good for GAS, but I’m not sure if the other two secondaries are as favorable for him. And again, I’m not sure if the amounts, like 0.54%, would be considered low or not. Any help would be appreciated.
