Anything past 32 it with TCC has so much one shot potential at 55. And the Moonlight spear compliments bead well, they WANT to get in, they get MAD at your poke and roll, you pay attention and trade their running attack for a SS or Bead, they fall over.
It's pretty much just a build for being able to trade hits really easily, although I can also dodge-poke if I wanna. Very nice if fighting multiple people at once, because there's a big chance you can hit them all at the same time.
Yeah, because 120 was standard in DES and it carried over, despite the very different landscapes of pvp and effective stat distributions. Thats the reason, anything else is secondary.
I agree that there are limited effective builds at 55, but there arn't all that many effective build combos at 120 either. Its almost all 50/40/40/30 or 40/40/40/40 builds.
its an old thread but https://soulswiki.forumotion.com/t17534-sl-55-why#340681 I outline the basic build types for 55 and 80. It actually decreases as level gets past 100 or so, because at that point pure builds (1 damage stat) are no longer viable, and effective hybrid stat spreads are not widely varried.
