Are these new attributes on mods worth it?
I don't seem to have seen them before: Deal 1 instance of Elemental damage/weakspot damage
Should I prioritize those effect among any others in those specific mods?

Resonance mods are only available on hand and pants. It can be bis for long fights like bosses. You want to aim for two resonance attribute depending on your build.

Unfortunately I am using bomber so the weakspot one won't be very useful :( too bad this one has 2 of them

these mod is superb on my build. im going off meta using dual fury shotgun this season. its fun

[kavinh]

great for corrosion shotgun since they can fully use both crit and elemental damage and doombringer with those hunter boots. besides those i don't think it's particularly good

yep I agree, good point. Too bad I am not using it, but that gun is definitely a lot of fun, maybe in the future.
