I think it's not that bad. Wahl, who can cancel Magical Barriers, can also cancel Magic Barrier Particles. The reason Freed's Jutsu Shiki can block attacks is probably because it can break down the Ethernano from them.

Also, if Evergreen can manipulate Freed's runes, it's not unreasonable to think Laxus learned a thing or two from Freed.

The Red Lightning attack is hard to justify though, since not much has been explained about. I must say that it's nice that something semi-relevant happened in Ryuuzetsu land.
