1) Commendations could be abused. A party of 3/4 or 7/8 queue up with a low population language option, and one friend queue up solo. That group gives all commendations on the last player even if they're AFK. My extreme example takes a lot of setup and some luck, but it highlights a potential exploit.

2) This suggestion feels unfair. If you were to vote on lunch options, and 3 friends voted for Thai and 2 new interns in the office voted Pizza, Pizza should not win just because the interns were new. Again, a lack of balance.

3) This sounds like an instance of a group of friends or maybe a premade from one server queuing up and they have the understanding that they were just there for the first boss to farm. It is just poor communication on their part. Even if they select a reason for it, it would have likely been arbitrary and you would have lost that vote anyhow. So for this one, I'm saying you have a good idea, and also I'm sorry it happened to you. :x
