Nice try Nexon but Dawnveil does not equal Masteria!

Probably a different team.

Also, I wouldn't be surprised if they kept every mob that was every added at any point in time, and they also likely don't have the sprites separated from the mob itself, so when they have 10 placeholder mobs for some reason, they didn't reuse the same single spritesheet but have 10 in the data, 1 for each placeholder. It's pretty inefficient...but to be fair this is an old game and it likely wasn't a consideration when the game started. They're in too deep to do something about it now, if true. At least, that's what I imagine. They say Hindsight is 20/20 for a reason.

Having trouble following that stream of consciousness there.

At any rate "This is an old game" would be a justification against this kind of inefficiency. You had less to work with then, so you had to run a tighter ship.
