A LOT of people has been discussing the new star wars movies lightsaber design. Mostly about the guard being ineffective and what not.
Now, i want to tell you guys what i believe. I believe the guard is unnecessary, if it is used as a guard. From what i have seen in the movies, i would conclude that the lightsabers aren't able to grind against each other.
Instead of using it as a guard, i think i could be used for attacking, or maybe blocking while attacking. example: a full front attack is being made. the wielder of the new lightsaber performs a stab, using the "guard" to stop the enemy's attack and at the same time stabbing the enemy.
These are my thoughts on the new lightsaber. Sorry about grammar and spelling, not native english.
