not really. crushthrough is almost as silly as polestagger is
I can see why people want to remove Polestagger, it´s an unfair advantage, but remove crushthrough from Mauls and what do you have left?Shit!.
Also you need a strength-orientated build to reliably crushthrough with everything but the great maul.
And the Great maul is short, slow as shit and 3 Slots(Meaning you can only have crap weapons as backup).There is no melee weapon except for the long maul ingame that is slower than the Great maul.
The Mauls are pure Support weapons.They rule in Groupfights, but in one on one they are easy to beat if not used by a very skilled person.
A person playing with the GMaul who mastered it´s style can obviously seem OP, but that´s the same for every weapon.
Crushthrough-Weapons surely can be annoying as hell, especially if you are a biased shielder in that matter, but they add to the diversity of the game.Without crushthrough you could let another bit of Battle-awareness slip(The Part where you check the enemy for Mauls), making the game more repetetive and boring.
