Why GGG remove a unique feature stand out from the rest

It is the parry version of "Magma Barrier".

Why not keep the original skill and add a new one, instead of deleting such a well-designed and unique gameplay mechanic about parry version of "Magma Barrier"?

I specifically started playing this game for this gameplay style, only to find it removed in the new season. What a pity!

It's such a unique fun gameplay style – especially when you compare it to other similar games.

Moreover, this mechanic aligns better with the game's developmental vision - be more Souls-like.

I don't understand why GGG decide to remove it and want some explanations.

And still not fix the Magma Barrier bug
