Shield or Armor?

Usually I go with shield. Because they recharge and health doesn't. Only with a couple of Frames like Inaros or Valkyr I go with full armour, because its their strength and you can build nicely around that.

In any case - not getting hit is best, so I concentrate on mobility and devastating melee when I can.

Of course I'd make sure first if the inscriptions actually work in Anthem before I'd bother in the first place.

I usually went with shields since they regenerate.

There's a clear answer for each javelin (with maybe the exception of the ranger) based on the resource they can regenerate. You want to stack your multipliers there.

Colossus - armor (best defense, the component that heals on melee kills)

Interceptor - shields (masterwork throwing stars, components that buff shields at expense of health)

Ranger - mostly armor (the components that restore armor mostly outweigh the shield regen, but a case can be made for shields if you melee a lot or are running radiant fortress)

Storm - shields (has natural 20% DR that applies only to shields, so shield increases are more effective)

Easy, both on components. Then with sigils. Colussus, armor. Everything else shield.

Well, you gotta go with whatever you get in the end because we can't switch out inscriptions. Overall I find base shields of the Interceptor too low so I prefer % armor increase as it gives much more in total value opposed to shields. Also shields regenerate on their own and I can refill armor with melee kills on Way Of The Bold. I hate how low the stats on universal components are though and that I basically HAVE to use 3 of them with 2 of them being totally useless for me but because of their inscriptions they are better than using specific Interceptor components. The system is just totally flawed in every way - I have never played any loot-based game that is such a mess in terms of inscriptions, damage scaling, useless items...

Replace luck with Armor/Shield
