For me, Deep Dungeon was a disappointment. I like the randomly generated concept but everything else sucks. There's a huge of BS and frustration required to undertake this dungeon. It's the high amounts of fake silver chests that are mimics or explosions which start to become aggravating when your gear is over 25 and can only get upgrades from floors that doesn't sync your gear. Not once have I seen my gear go up while it was synced. My second issue is that there's no way to select completed floor sets which is just plain stupid and makes leveling your gear that much more tedious. I get that SE wanted to make things hard to upgrade but they could of at least made it so we could of selected a completed floor set. Instead, you're forced to reset and repeat the same shit on the same floors getting the same silver chests that won't upgrade your gear until you reach a floor that matches your gear. I was excited for this dungeon when it was announced but now, not anymore. I'm over it.
