I will admit, that the Group queue returning is great for players that like to do so.
Group queue is basically beneficial for one thing certain achievements. That require you to make sure the other two teams don't get too 200 points and stay under that. But otherwise, this queue system is flawed for two reasons. One is not really a group queue. Its an everybody queue. The other is as a solo queue and is superior because its more a competition. .
What they need to do is make the group queue an actual Group Queue, The requirements either being you have to have at least four people in your team. Duos, those who are partners like husband and wife, boyfriend and girlfriend, or best friends, or even husband and husband or wife and wife etc, Can find each other and can team up group together to enter. .Or they can make it so you have to have one other person in group to enter this queue in your group to queue up for this Can be either a duo or a 4 man. Either way one should not be able to enter as a solo and this coming from a person who solo queues.. But either four man or duo should be required for this queue. Being solo is what the what the solo queue is for.
Pros and cons of the all person queue.
Pros.
1.Better able to get certain achievements.
2.Faster queue completions.
3. Being able to play with friends and loved ones.
Cons
1.Unbalanced because of how it is with the mix of various types. 4 mans, duos and solo queuers.
2. Is the biggest con of this mode. Face Roll over the other teams is much more common. Unbalanced because there are better players then others. You can get solo queuers like me who obviously suck and not the best with mechanics that like to do it for the exp and even ap points. Along with having fun, not as caring for deaths because of the respawn.
The All people queue is more often then not a Face roll queue and the way it is now makes it that way. But if you remove solo queuers and then make it so you have to at least a team of four to queue up then it. Then it would be so much better for this type of queue and maybe reduce the face roll possibility.
Right now where one group that is very good, goes against other groups that have mixes of duos and even solo players like myself and you can how the score looks during this. If your lucky a solo player you get into a group with very great players that are face rollers and then dominate the other two teams. Getting even an achievement for it if the other two are below 200 like I said before. This is the prime example of what you typically see in this type of mode.

Solo only queue pros and cons.
Pros,
1. Competitive: Two or three teams can be neck and neck. Making it more fun, and that score above would likely be so much more differant in a solo queue. One two teams or even three can be neck and neck making it much more balanced for a completive game.
2. Much less of the face roll type of queue.
3. A chance for your team to catch up. Depends on how good you are or your group mates.
4. Its overall a much better experience and I think group queues should have something similar. That is why I'm suggesting these changes.
Cons,
1.Group dynamics if one team has a better set up of people, like a healer then they have advantage. If two team have this and the third does not then well. Third team doesn't stand a chance.
2.A bit more unorganized because well its solo queues and people myself included might run around in various directions. Teams split up and well that is something I have to work on not doing and maybe sticking more with the team.
3.Certain achievements are much harder to get. Like the ones that requires the other two teams to be less then 200 points.
So gist of what I want to see is.
1.Group queues for people grouping only.
2.Solo queues for those queuing solo only.
3.Didn't add these above but adding them here. a Third mode for those that want to do death match that is a queue just for that. So Randoms would have all the modes, While Death match would have just that mode and there would be one for both group and then solo. Basically four modes, not just two. I know that this may splinter things up. But there are those that really don't like the other modes. They just want to kill other players. They should be able to do this. Without the hassle of getting the other modes.
4. So a lot more stuff they can do with battlegrounds to make it so many more players do all the modes and not just one mode even to go with this. One is to add in dailies for doing certain queues. Maybe unique item sets and outfit rewards that only go with the group queue, that can't be got anywhere else, unique outfits and sets that can't get anywhere else but the group queue death match only mode. Same for the solo queue, sets and outfits that can't be got unless you do the solo queue. Then the same for the solo queue death match only mode.
So there is a lot they can do with the battlegrounds and that is the reason for this thread.
