I'unno. It's more like the point of Mysterious, Record Erasure and Mask of Metal to begin with to leave an enemy guessing.

I'm not against Spirit Mirror's fiasco, I think it should get some form of indicator, yes, but the real eyebrow raiser for me is why bother with the mentioned passives if someone can just see your sleeve cards anyway due to your char's many cool and sparkly overlays? The VFX indicator would be a QoL to save time double clicking someone to see certain buffs in the end, as long as it doesn't touch the mentioned passives, or make them enhance negatively the purpose of an indicator, as dumb as it sounds.

I think it's fine for concealment passives to actually contribute more to keeping you unpredictable and unreadable for your enemies, as annoying as it is to be on the receiving end of that, I understand. But if these skills were not meant to be like that, Dev wouldn't have made them, and made the meta-game of knowledge more fair/gave those a form of counterplay.

One thing is actively hiding your surprises with passives made to bamboozle enemy players such as the ones mentioned, which is very, very limited to Heavy Armor + Helmet item combo or Spellthief for 1 SP, another is saving a ranged/projectile user player's time from double clicking an enemy in paranoia their stuff will be uno reverse'd.
