Nothing inherently "wrong" with it AFAIK, aside from maybe making it impossible to put a keck clip on the joint.
But to my non-educated ass, it seems like a clear demonstration of improper technique.
Sure, it works, but that's just not how you use a dewaar joint...
It just throws up a red flag for me.
(If they'd said something in the massdrop about it being intentional, either due to lack of traditional joints or as a style thing, it wouldn't worry me, as it's basically the blower saying "look, there's a bit of an odd element to this, but I recognize that it is odd." The way it actually went down feels to me more like the blower fucked up a little, and either a) hoped the buyers wouldn't notice, or b) didn't notice themselves... Either way not a good thing...)
BTW,
@DieHard I'm not ragging on your piece specifically, just the whole vibe of the simba massdrop.
For the price, you got a pretty nice piece there
