I would like practice mode for raids

Seems like dungeons are getting harder and harder. I love a good challenge as much as the next guy. I'd rather not flood duty finder trying to learn something, and starting a learning party can sometimes take a great deal of time depending on the content. What I would like is a solo or group practice mode where I can skip to certain phases, and set my own dungeon parameters.

I understand a solo mode would be incredibly difficult to accomplish, because of giving away fight mechanics through the movement of NPCs. Which would be giving user dungeon parameters to allocate for commanding NPCs. Not unlike the gambit system to FFXII, but specific to each raid or dungeon.

For example, If enemy skill = "Death sentence" > healer skill = "lustrate". Yet, I would be just as please to see group practice mode, all the same.

Yappers

I guess the easier approach for both players and devs to take is handling it like with the primals.

Like Coil-Normal, Coil-Hard and Coil-Ex in some way, less instant kill mechanics in the normal and hardmode to practice for EX.
Of course the good stuff is only obtainable in Ex.
