(B*tch please, Yin Yang Release here i come

)
Sorry about the late reply, i tend to reply almost immediately.
Advantages of this Method
The fundamental advantage that this method posses is sending out some sort of high speed projectile, with high penetrative powers. This automatically overcomes Earth Techniques/combinations which seek to lock in/encase the user in some sort of dome. Having the natural advantage over Earth simply furthers this effect, allowing even the lower ranking projectiles to do some damage to an Earth technique.
The concentrated beams of lightning which don't branch off into multiple projectiles retain their full destructive capability allowing them to be more efficient against Earth Release techniques. It mainly constitutes to them breaking through Earth walls defenses seconds quicker than the latter method. While it might not seem like much, it could be all the difference in a fight, believe me, i saw a Scorps and Scary Yamato fight xd.
The beams which contain the capability to branch off into multiple projectiles can be used to exceed the width of an incoming wall of water so the entirety of the technique isn't redirected towards the user as the lightning is conducted along the water. Another rather obvious advantage of this method is to strike multiple foes, clones without much effort and to an extent summons.
The ball of Lightning seems to have an exclusive advantage of being concentrated into a fairly small object which could blend into a wall of fire when used simultaneously.
Disadvantages of this Method
This method does entail some daunting disadvantages. Wind is a highly projectile intensive element, its rarely used as a hand to hand offensive. The nature of wind means that gusts of wind that span a large area would insulate the bolts of Lightning, whether singular or multiple and they would effectively become useless.
Another disadvantage of the nature of these projectiles goes back to its relationship with water. Water is another usually large scale technique meaning if a wave of water is tall/wide enough it can absorb all the bolts of lightning and in turn increase the strength of the opponent's technique to a whole new level.
Strategies in using this method
I'll be as concise as i can with this section, i tend to go ramble on when i'm talking about combinations and tactics.
Basic combinations that require no explanation include:
Fusing with walls of water to electrify them
Splitting to avoid hitting into an opponet's Water Technique
Breaking down multiple earth walls by splitting
One combination which just came to mind is using this to break down a defensive wall and opponent constructs and then following simultaneously with a Large Scale fire release technique. The lightning would surely cancel out the wall, leaving little to no time for the opponent to counter the blast and the technique being too large scale to simply "avoid". Going underground is a death trap in our RP seeing as everyone can learn "Earth Release: Swamp of the Underworld". Under the right conditions, this attack will hit 100%.
Another combination could be using flames to mask the presence of the projectiles (they can move freely within eachother), causing the opponent to try to counter the Fire (most likely with Earth or Water), allowing the lightning to break the walls and if water is used then the splitting ability to avoid the whole width of the water by edging to the far sides.
Trapping the opponent in some sort of Earth Dome and then using Lightning release to be conducted along it would be another efficient tactic to use Lighting projectiles. However the dome cannot be touching the floor as the current would simply drain away pretty swiftly.
