Main Scenario Restriction Bloodstorm - Very Very Bad idea.

[Reynhart]

Are we really going to suggest these mechanics are difficult to learn? Gaze, you look away. Towers, one person stand in the glowy spot on the floor. Giant arrows targeting one person, everyone stacks.

Considering they had to nerf Blighted Bouquet because "Stopping any action" was apparently really difficult...yes, we might suggest that

But the problem is not the difficulty, but the punishment. In dungeons, failing these mechanics won't result in a wipe, so you'll have time to learn how to deal with it by yourself.
In raids you fail a stack, you wipe, you fail a gaze, you wipe, you fail a tower, you wipe, you fail a split, you wipe...

Touche.

Yes, but they wouldn't be going into raids. If you were jumped ahead to Stormblood, it would be the equivalent of Heavensward now. So you would be doing dungeons and occasional easy mode primals. And like I said, guides are available as would be a "Proven Grounds" type requirement.
