Popular opinions on best armor builds?

[Linktech]

I'm looking for popular opinions on armor skills or full builds in general, like a build for sniper, build for roller, build for .52 and so forth.

Anyone willing to share their insight?

People like to counter the .52 Gal.by using a Defense Up Main. The .52 Gal. kills in 2 shots, but with a Defense Up Main it takes the .52 Gal 3 shots to kill. You can counter this by simply running 1 Damage Up sub. Seriously, one sub is all it takes.
