I have a vague notion the iron armors were a bit different on euro, not initially but in later years they were changed I think. But maybe I mistake that for those specialty armors that were gotten from quests occasionally, those were just colorized or some color filter was laid over them.
Problem with the ideology of this ace mir and most private mirs is that they scoff at anything under level 40 and the increased experience x8 makes it not worthwhile, pple see levels under 40 just as nuisance to get over with as soon as possible, they just close their eyes and force themselves to level blind through.
Euro mir in its later years was seriously unbalanced in that koreans gave $%^&* about changing things for levels under 40 but on the other hand in euro later years they threw in things like that frog cave for low levels that nobody would give a hoot about if there wasn't a midboss put in.
Mir is essentially under level 40 game, in which endgame is somewhere around level 45, it is not made for more levels as far as content goes. You don't need to be much higher level than that except maybe if you wanted to be able to solo every single last boss in game (but with today's overpowered items pple can solo them or near solo them without needing any higher level) but mir is not game meant to solo bosses.
Ideally server would be set up so that you'd start getting level 40 pple a year into the game, like it was on euro, not one or couple months like it is now.
