all greatswords got buffed for like 20 base damage on average, which was pretty needed to give them a point vs straight swords imo.
And also
For UGS fans the Zwei got +5 base damage so is now 145 and the Astora got +10 base damage so is now 132
Probably didn't get buffed enough imo. astora still very low damage for a UGS but looks cool and has a spear like charge special.
And there are other UGS with zwei moveset that do more damage.
the better than zwei UGS I mean are profaned greatsword and the lothric knight greatsword, they will likely become popular. I have both of these upgraded and they are lovely for pvp, and even non boss pve with the lolstabs. I hit people a couple times with profaned special and it sends them flying through the air on their back and lights my sword on fire
The flame ultra will always be way higher damage and only need strength, but its 2h moveset is shit imo and it looks fugly. What I like doing with quality builds is if you have 27 str and 40 dex then when you 2 hand the weapon you are effectively 40/40. (I recommend base 27/37 because cool dex ring).
