As it is now in Lockdown, you get hit, and you have a split second worth of invincibility, just like in the clockworks (but supposedly much shortened). I personally find this to be unnecessary. Sure, one person will easily be taken down by a group but because only one hit of the group at a time can be registered then the person can output a lot of damage first. If you're being hit by 3 or 4 flourishes at once it's not like one always hits and the others magically pass through you.
So how would this affect Lockdown? For most, it wouldn't make much of a difference but there is one thing I am looking at: cutters. Because of the invincibility frames, the ghost slashes generally don't hit, even when the enemy is pushed into a corner. Either a severe shortening of these frames or complete removal would make cutters more viable weapons, and, indeed, increase the amount of variety in Lockdown.
That's a great idea. Lets make it so strikers with FFs or BTBs ASI VH can just spam attack and hit you every single time. Maybe we should also take away the health decrease of the strikers. And put it on the other two classes.
At least right now they have to shield cancel first. A good guardian can use that second to hit.
