WHM Eye for an Eye poll

[Kyomih]

It's a great skill and I use it in rotations during hard encounters and on big groups in farming content. I don't think I would swap it with anything else in my cross-class skills.
However, it's not always useful. Ie. Coil T2, non of the Nodes or ADS trigger Eye for an Eye. Most probably because all their attacks are counted as magical only.

This part is undeniable. WHM get 7 potential cross skills, and can slot 5 at level 50. The options are Physick, Ruin, Thunder, Virus, Eye for an Eye, Swiftcast, and Surecast.

• Physick is the same cast, cast speed, and MP cost as Cure, but cannot proc Freecure, so you should never cast it over Cure.
• Ruin is less potency than Stone for the same cast time. It costs less MP than Stone if I'm not mistaken, but it's worse potency per MP and doesn't cause Heavy. It's not even close to Stone 2. The only situation you should cast it is if you need to damage something immediately but don't have enough MP for Stone. At level 50, any situation in which you or your party is counting on one last damage cast from your sub 100 MP WHM is a situation you deserve to fail.
• Thunder is a DoT spell that stacks with Aero and Aero 2. It is worth casting in situations where you are damaging things because it does more potency per cast time than Stone 2.
• Virus noticeably and reliably lowers the damage the tank takes, and you have to pick it up to get WHM anyways, so take it.
• Eye for an Eye semi-reliably lowers the damage the tank takes, but requires a bit more ACN levels to pick up. If you are willing to grind it, there's no reason not to use it.
• Swiftcast is great for reducing the cast times on Raise, Medica 2, and Stoneskin. It is also useful if you need to move while still healing. Takes a bit of work into BLM, but it makes it worlds easier to Raise people. Not mandatory mandatory, but not having it WILL cause you to wipe in situations where you could otherwise recover.
• Surecast isn't very useful except in situations where the entire party takes predictable damage; in these situations it allows you to start casting before the damage comes and then immediately heal it. It's also level 6 THM, so you can pick it up on the way to Swiftcast.

Swiftcast is what I consider the ability worth grinding for. Virus you'll get on the way to WHM, Surecast and Thunder you will pick up on the way to Swiftcast. Eye for an Eye, while useful, isn't strong enough to justify grinding the extra 19 ACN levels unless you are heavily into min/maxing. That said, if you have those levels for whatever reason (whether you ARE a min/maxer, or you like playing Arcanist, or whatever), Ruin and Physick are total garbage, and it is not.
