I can't fathom how any group would be able to get past Allagan Rot without specifically calling it out in voice chat. If you can't do voice, you should not be doing turn 2. Seriously.
You have to wait until the debuff is 7 seconds, you need to find one of your numerically assigned party members and give them the rot, making sure beforehand that they don't already have the immunity, then they pass it on to another person after 7 sec. and so on.
Every single time, we wipe because one of the TWO people in our party wasn't in voice chat. You need to call out when you have the debuff, call who you're passing it to, and make sure you don't pass it to someone else on accident or the party will wipe. And this happens TWO times throughout the course of the fight. Oi ve.
Is there any way to do this or should we just reject anyone and everyone that wants to do turn 2 but can't do voice, is it that much of a necessity?
