So... you want this change added so you can practice the rotation you don't even have. Am I getting this right? Surely I've crossed a wire somewhere?
The second quote is also the answer to your trying to pit Penthea and Momomi's comments against one another. If your proposal - as you've stated
multiple times - is that it's okay for the higher level abilities to be synced
so far down that they don't even do damage, then yes. Yes you would be kicked faster than an Ice Mage because at least an Ice Mage does damage.
This is actually a big part of why I hate Eureka. The Relics were my reason for doing roulettes/dungeons in ARR/HW. I've been omni 70 since... I don't know, October? I ain't got no real reason to do these things. I sure as hell ain't sitting in MSQ Roulette.
The part where low level feels terribly just seals it.
