Per Reddit: Calling for a blackout of ME:A multiplayer.

That is melee. If you compare it to an adaptive war amp for actual power damage it only adds 15%. The closest comparison to what the weapon equipment will add baseline (Turian Havoc weapon passives+ turbocharge) the majority of weapons are still garbage and underperform - and turian havoc has tons of other buffs aside from straight up damage. The less bad weapons just feel normal.  All that amp will do is make weapons more normal feeling and they shouldn't feel normal with an amp they should feel upgraded. I can almost guarantee you though it won't be a 75% weapon damage boost, and if it is I'll laugh if the majority of weapons are still trash even with the amp plus a havoc passive and turbocharge. 😛

The only way the vast majority of weapons are viable to even use with or instead of the baseline few superior weapons is to have them VERY upgraded (item levels, leveled barrels, character passives, etc.).
