Even though I don't use them anymore. I hate how when you charge the Gran Faust and Divine Avenger you back off with your back up against the wall and the three swords explode once they appear. Also the nerf on the spread of the 3 swords renders the charge nearly useless. Additionally, when you charge them you back off a little bit, taking away from the number of enemies you can hit with the initial charge.
My suggestions:
-Fix the glitch where the 3 swords dissapear
-un-nerf the spread of the 3 swords
-take away the stepback when you charge
Hopefully this would help make the charge more useful.
You want one of the most powerful charge attacks in the game to be more useful.
