Mod Help

Your Fives is pretty well modded, though I personally would never have taken the diamond or circle mod to 6A with such low speed secondary stats. 

Your Rex modding needs some work - he needs to be much faster. You should be aiming for at least +15 speed secondary on all the non-arrow mods. Again, you’ve made some questionable choices taking some of those mods to 6A. I wouldn’t do that for mods with only +6, +8 or even +10 speed. 

Your ARC trooper only has 4 mods equipped. He needs 4 offence mods and 2 health. Offence primary is needed on triangle and cross. I personally run him with an offence primary arrow as well, but many prefer speed there. 

Echo needs 4 offence mods and most tend to run 2 potency mods alongside that. 

My general advice on your modding is to stop taking poor mods to 6 dot. You’d be much better hoarding those resources until you get a better depth to your mod collection so you can take the best ones to 6 dot and then the upper reaches of 6 dot. If speed has only popped twice on a mod, I think taking it to 6 dot is a waste for someone in the early game like you.
