It's funny because the estoc (same moveset as rapier but just more AR and maybe a bit longer) is god-tier in Demon's Souls PvP. Literally the single best PvP weapon. Now apparently it's a harmless toothpick, haha.
The Estoc was god-tier in Dark Souls as well. Maybe not the single best, but behind the BSS it was the best straight-sword IMO.
Still not sure about the DS2 version, but my early play with it shows promise.
