I agree that balancing the other melee jobs around a spell is kind of silly, and maybe they should reconsider that part, but it still doesn't change the fact that Rudra's Storm did too much damage.

The issue isn't rudras itself and created a lot more versatility in end game content which I think might phase thf out.
There was no "versatility." Everyone started playing THF because Rudra's Storm was overpowered. Now it's getting nerfed. Yay.

(which I would personally suggest buffing other DD jobs).
I would rather not all the content in the game be melted like Rudra's Storm is doing to it right now. Then you're gonna say "but but but Samurai is strong too!" and my response is relax, they said they were adjusting Samurai as well.

Considering something doesn't mean doing something. Not that long ago they were also considering adjusting 2hd weapons to balance with 1hd and we are seeing how that played out... for all you know ardor is there answer in balancing sam as laughable as that is
You're right, and by your logic, they might not even nerf Rudra's. They are "considering" those dagger changes just like they are "considering" SAM changes.

Not that long ago they were also considering adjusting 2hd weapons to balance 1hd
Source? Also, they did buff 2 handed weapons, considering the huge damage augments they get from skirmish.
