Removing equipment to manipulate Alliance Roulette is pretty common in my data center.
There're lots of people openly embrace such idea and even share this exploit to new players. There're even tutorials for it in private discord servers and unofficial forums.
To make matters worse, even if you queue specifically for certain high level alliance raids, The Ridorana Lighthouse for example, you will see many people withdrawing during mutliple DUTY POP. A work of a certain third-party tool I'm sure.
Knowing this, I avoided doing Alliance Roulette once I reached max level in ShB, and will do so again once I maxed out all my jobs in EW.

As for addressing such exploits, I think lowering max IL in synched Crystal Tower raids to a degree that that players actually have to do mechanics is a good way to go., but that's just my opinion.
