Greatswords moveset isn’t redundant, combining lights and heavies for horde clear is its defining characteristic.
Heavies uses are: as opener \ wide dragged swing vs surrounding horde \ assisting teammate or when elites are mixed in.
Lights serve for preserving attack initiative (replacing the need for push or block) \ when you flank a horde or enemies form a low angle of threat \ to finish off lone survivors after heavy swing (not wasting time for a full heavy).
I’m glad they keep the classic moveset, its one of the reasons i keep coming back to play some VT2.
There is really a weapon for every taste in this game. What stands out to me about greatsword, is how creative it feels, because its very reliant on swing hitbox drags, and combining lights and heavies to do horde clear. Which is simpler for meta weapons (and they can do more elsewhere), but they lack the satisfaction of clever and fluid comboing between lights and heavies, they’re too simple - usually one attack type per type of threat, with maybe a block cancel. Or like halberd - where youre locked in a fixed repeating combo (L - H - L - H). With GS you can make the next swing whatever you want it to be, and it always looks great since any type of heavy attack (both of them) transition naturally into light attack, and vice versa (the blade keeps moving in x shape, there is no sudden stops or reversing).
I like the damage buffs too, they reinforce the weapons concept. It was lacking a bit in damage output, now it feels more rewarding to extend those swings.
