added lightning % aura/node/gem

Much of the problem with pure physical damage lies in how it can't cause status ailments. Pure physical can't cause status ailments. However, with the gem, added fire damage, and the aura, hatred, physical users can scale elemental with their physical damage. However, there is no way to scale lightning damage with physical damage. I propose either
A. A physical to lightning aura - May be too OP
B. A physical to lightning gem - there's already an added fire
C. Make the node after the two static blows node add 20% of melee physical damage as lightning damage. - May be OP as well.
The thing is, freeze and burn is cool, but being able to shock and do 120% more damage is hugely beneficial in favor of elemental damage. Making an added lightning node/gem/aura that converts part of physical as lightning allows melee physical users be able to inflict all 3 status effects without having to use lightning strike.
Then again, I guess people could just use lightning strike... :P.
