More Efficiency Mods for MELEE Weapons like focus energy please?

[MadMattPrime]

Right now there is only 1 40% Efficiency 60% Elemental mod for melee weapon which is Focus Energy which is electricity only. The switch on Heavy attacks focus melee I believe we should have more efficiency mods as because there are other factions. Corrosive, Magnetic and Radiation are the only possible combination as of now. Gas, Blast and Viral ain't possible without other efficiency mods.

While I agree, I think it should be expanded on even further than that! 

Not just other elements+efficiency, but efficiency+Combo duration, efficiency and Combo chance, efficiency and range, efficiency and Atk speed. There's alp sorts of interesting buildcraft potential in these mods, I'd very much like this direction to be expanded on

Maybe a sentient vault...with more corrupt/extraplanar mods.

if they were a 60% element + 40% efficiency for the 4 element, if would mean that :

with 2 of this mods, we can have 80% of efficiency, that is good, but the half of the max.

if we want the max, we would need a third mod like this, or 1 mod like this+the mod that give 60 efficiency.

 

it forces you to make choices, so it is good.
