I'm debating with someone(surprise) about realistically, just from regular looting how much meso could you get in the best possible circumstances. I know there are a few things such as "PDR/Level/Skills/mobility" that effect this, but I'm pretty confident it's going to be ridiculous anyway.

So what mob in maplestory (common mob, no boss tag) actually drops the largest sum of mesos? I'm assuming it's the new monsters in future henesys?
