Proposition: You aren't gonna be able to crawl ToV with 700 random people in zone, or even push a gating mob properly. Suggest making it a multi-guild event with a level requirement.
- Even this method is going to have an absurdly bloated number of people in zone, but it will be more manageable.
- Problem makers can be reported to their guild's raid leader, who can then deal with removing them if necessary.
- It makes loot easier since you can split it via guild and they can use their own loot councils or DKP systems internally afterwards. Less wasted loot and it's not 700 people random rolling for stuff.
