Went a little hollow in PVP after respeccing my 50STR build to use the Black Knight Greataxe. I know, I know, it sucks. But I didn't think it would be that bad. The main problem is that there is a very small "sweet spot" you need to connect with to get full damage. You could hit a dog with the blade of the axe and one shot it for 650+ damage, or hit it slightly closer to the pole and only get like 300 damage. I wouldn't mind it if the difference wasn't that great and if it wasn't so hard to land a hit with this thing in the first place in PVP. The lead time on swings is slow, its poise damage is beaten by many other STR weapons, it eats up stamina, it's heavy, requires too much stat investment and the scaling isn't great.
Brought my character to 160 to try to make that work (because of the additional stat investment needed; I was barely getting by at SL150 with less VGR,STR, and ADP than I had before).
But after about an hour and 2-3 wins (tons of losses) I conceded that I didn't like this build at all and I sought out another soul vessel.
... Now I have 60VGR, Fire Malformed Club+10 and flame weapon. It's so much better than the BKGA it's depressing. Better poise damage, can be imbued, can be buffed, much lower stat requirements, much better base damage (that completely nullifies BKGA's shit scaling bonus), better moveset for PVP, much lighter. The only caveat is that I need bracing knuckle ring+2, because the durability is so bad that it would break in mid fight, but it's light enough that I don't need royal soldier's ring+2 anymore to keep under 50%, so that's fine.
Still keeping 50STR for when I want to use my other favorite STR weapons. But... comparing malformed skull to Grym Greataxe (one of my favorite weapons in the game) is depressing too.
