There’s a problem in that it’s mostly veterans who are able to clear 90-100 to begin with. Less extreme players just won’t be clearing these floors, consequently making the ml bookmarks a veteran/whale exclusive reward anyways. Still, it’s definitely deserved considering the effort or money people might put into the game.

A normal player might be able to raise good enough units and gear within a month to clear Automoton if they tried hard enough so I guess that’s SGs intention. But just seeing how hard these floors are for veterans, the ml bookmarks being gated by such difficulty is a slap in the face to non-veteran players when all the rewards prior are so trash (excluding the molas and charms).
