How could you do this to AST?

bardam mettle are one such few examples I love using, something about that dungeon put a major dent on tanks no matter how much you spam regens cause idk some of these dungeons seem a little too bad ilvl sync , while you have dungeons like the current matoya dungeon that the mobs feels they barely even do damage.

Bardam's Mettle's difficulty was due to a 27% spike in gear Def and M.Def from ilevel 270 to 276. Matoya's Relict feels weak because the average tank goes in with 20%(i500) to 45%(i530) more Vit and 7%(i500) to 14%(i530) more Def/M.Def than the dungeon is designed for (i470).
