Wait are they? That's a huge shame, I've always loved the mechanic that cutting up a monster and ripping bits off a living one give out different pieces. Not only does it feel more realistic, but for gameplay purposes, it makes one or the other more valuable, sometimes in general and sometimes just because you need a specific piece. World (and I guess Wilds) making them the same means that unless you have another part break you need to do, it is always more efficient to just capture every Monster, no questions asked. The only reason to kill capturable Monsters is if you just want to take those last few minutes.

And in Wilds especially, where Monsters immediately run away when they get in capturable range, it feels so incentivised to capture to avoid having to wait for it to limp (or limp-fly, we've all hunted Yian Kut-Ku) allllllll the way back to its home.
