ARMOR MOD

hovering or not you are still having reduced weapon damage. This applies to every fusion mod, the negative effects apply for every situation. However with the right cryo pod perk you can halve the negative effect, i suggest you skip using this mod entirely unless you not planning to take the combat tree passives that gonna give you more than enough hovering time.

imo the only useful fusion mods are;

fusion mod of adrenaline  - great for anything other than architects but even then it isnt terrible when it spawn mooks, just less useful than in general.

fusion mod of health - if you wanna be super tanky

plus if you prefer raw damage then there mods for tech and biotic damage or flat power recharge speed then go with them. Though my opinion powers becoming an utility above lvl30-40 on insanity, adrenaline is a better choice as it can be really a lifesaver when you are dying but you get a clutch reset. 

It all depends on your build though, dont wanna talk you to anything. I've seen some videos on YT in here that totally proves the opposite i was talking about,as this guy has some crazy powerful builds for each playstyle. If you can afford to hover in the air for a long time and like to do so, then use it. There are a few augmentations that work only while hovering and to utilize them fully you might wanna stay in the air for longer.

The more important question is: Where is the armour mod that increases weapon damage, "but reduces all other damage by 20%"?

I have a run&gun legionnaire character that does not seem to benefit much from any of the currently existing fusion mods.

In other words, I prefer playing that character without any armour mods whatsoever because none enhance its profile in a meaningful way.

There's no such mod that increase the weapon damage sadly.

For my soldier i used the fusion mod of health which trades 25% of your shield (50 without the perk) for an extra 100% health. Sadly you acquire that only late game so you wont benefit of it much for long.

Maybe the 50% shield for 50% (25) of your health.

But if you dont wanna any of those then put on the adrenaline. Recharge penalty for your powers but instant recharge on kill so you can spam powers left and right. Useful if your turbocharge went on cooldown and you kill and enemy a second later and bam, you can use it again. Also gives you more room for error if you miss landing your power or the enemy dodges it.

There isn't a mod for weapon damage, but honestly don't need one. There are many things that boost weapon damage already for example Soldier profile, top tiers of weapon skills, tactical cloak, kett unity armor.
