The problem is the blade guards are pointless because they don't extend fully to the hilt, they have emitters extending from the hilt below where the actual blade emits. So they are blade guards that don't guard the hilt and are therefore worthless.
Was just about to say this lol.
Look where the lightsaber starts on the crossguard guys, it's not flush to the lightsaber, if your enemies lightsaber hits the part between the crossguard blade and the main blade it's going to cut through it, #reking your lightsaber and #reking your hand, leaving you truly #rekt.
I didn't mind the rest of the trailer and I have my hopes for this movie, but that one small detail did really make me cringe and smell the cheddar, it's a stupid idea that they didn't need to put into the movie.
