First of all I like all of these features but I have noticed some small problems. Mainly when it comes to premade groups.
First, player Commendations. I notice that premade groups cannot vote. And that's OK to prevent them from voting on their friends, but they cannot even vote for the random players. If you go into an 8 man DF and get 1 random and he is the best one great player helped out, no one can give him a commendation.
Second Kick for "Insert Reason". I was doing CT when one member of our group started saying racial slurs. I queued with some friends and I guess my friend tried to vote kick him for harassment which just made matters worse. This unnamed player proceeded to tell us he queued with his friends that they are 5 players and that they wont kick him, they proceeded to continue their harassment and there was nothing to do besides blacklist. It seems that if you have the majority in any dungeon you can never be kicked regardless of what you do.
Third, Vote abandon. There needs to be reasons for this, like family emergency or out of time or something. I was doing AK and there was nothing wrong, my team was not talking at all and after the 1st boss they all just vote abandoned. I'm not sure if it was because the run was not a speed run or what, the issue is nothing was said and they were a 3 man premade and just vote abandoned.
Their needs to be some sort of check for premades.
A few suggestions or "fixes" I would have are as follows.
For commendations, allow premade groups to give commendations to people they did not queue with, that way those 4 , 2 man duo queues can all give commendations. Yet this way they can never commend their friends they queue with.
For vote kick, make the votes of players queued together count less, maybe 1/2 or 1/3rd than solo players. This will prevent a 3 man premade to kick 1 person every time, and also it will prevent the other players from defending their friend when they know their friend was in the wrong. I haven't worked out the numbers on this, but there needs to be something to remove the full power of a premade group that can vote kick or save from vote kick. (they can be reported for false vote kick but there is no way to report defending a harassing player)
For vote abandon there needs to be a penalty for people abusing it, it also needs to have reasons. For an MMo that are meant to be social it really bothered me to see a vote abandon on something where no one died and there was 0 issues. Nothing was discussed and the premade just left. Reasons should be in the vote abandon, for example, Not enough time to complete, lacking damage (for those dps race fights like titan heart), lack of team work, and lack of communication. Something like so.
These are just some ideas. If you guys have any suggestions or feedback let me know. I'm somewhat just venting as well for my most recent encounters.
