It’s not like there’s a bonus from getting down to 0 HP. Maybe some day they’ll change pricing again and something won’t land on an exact 50 HP boundary. For now, you just have a little spare change in your pocket.
To be fair, I can see Deadpoo’s point. It’d be like having a canadian dollar in your wallet (or a NZ dollar for me, since I’m an aussie). You’re just looking at it every time you open your wallet, but you can’t buy a dang thing with it
What point is there to spare change if you can’t every buy anything with it?
