In addition to the people who cheat their ilvl to only get the crystal tower raids, you also have to contend with the people using alliance roulette to level up classes from 50-60 and the people who only ever unlocked the first two raids in the first place. There isnt an easy fix, because most of the problem is your fellow players. The best attempt at a solution i think ive heard would be increasing the rewards if the roulette spawns a higher level raid. Id be all for that. Or lowering the item sync on the first 2 raids to make them actually dangerous so people would be less likely to actively seek them out. Hell, id be all for deleting the characters of the people who cheat their ilvl too. If you need braindead content to level your characters then theres already enough of it in the game without ruining the alliance roulette. But im not holding my breath.
