It happens all the time. Just look for the mage staff symbol.
A lot of them do physical attacks because the casters used to just stand still and cast, which was really annoying because tanks couldn't resposition them. The ones that do are often sprites or casters but usually you are just beating up monsters.especially trash packs of dungeons where mitigation is most needed.
While true, if it's the same as all the other mitigations then it further homogenizes everything and the community has been complaining about everything being the same. SE can't win it seems, because either way someone complains.Magic only mitigation just means there's one less mitigation in the long run
If you mean Dark Mind, it gets forgotten about but so do most other tank flavor abilities:makes people forget about it entirely.Essentially, these flavor abilities are useless or used randomly to many players but are something that a skilled player can try to make use of in the right situations ie. buffed heal potency on WAR could help in a niche situation, Dark Mind can be like a bonus mitigation if actually used on magic and Camouflage can possibly be paired with certain other things. Bulwark can be timed for when it doesn't need to fight DoTs.
- Thrill on WAR is arguably not really needed for anything and may as well not exist. Yes it increases heal potency, but do we particularly need more?
- Camouflage is 10% plus physical parries so it's bottom of the barrel what you use when everything else is exhausted (which it won't usually).
- Bulwark while probably the best one used to not be due to RNG and only working on physical attacks - but PLD has so many tools that it's often hard-pressed to get round to needing Bulwark anyway!
How I used Dark Mind back in Shadowbringers was against a DoT-buster in E1S. There were a number of tank busters in a short space of time but one of them was especially devastating, with a Damage-over-Time potency depending on your mit. So Dark Knights had an advantage because of it being magic where they could use an extra mit so that the ticks were trivial.
