Let's look at the main reason for the complaint: Mommy and Daddy, I want the ball and I want the glory of scoring!!!
This isn't about bias, OP, or anything else. This is about those people that feel no matter what the situation is, they should be the one getting the glory. Mom and Dad, someone else, whoever, didn't give them the attention they need and now they must absolutely get said attention or they will do whatever is takes to get that attention, even if it's negative.
This is something I consider to be childish trolling. There is absolutely nothing wrong with any of the WZ's with regards to each class. I don't have any Imp's, but I do have a toon for every class in Rep. All of them are 30+, 1 is 50, and 2 are 45. This is about realizing glory doesn't all come from the score. If you can effectively help the team by stomping the enemy so they can't get the score, helping your team by strategic placing, passing, etc, that holds glory, too.
Some of my toons are great for ball carrying, passing, scoring, or variations of each. The point is, I know what my class if for. Stop crying for change just because you can't handle the fact that you don't get to score every goal. You are a just a selfish person that needs to grow up!
Here's the truth. WZ's and Raids are exactly the same in every way, with one exception. It's people you fight against, not NPC's. That's it. You must know your class and you must be situationally aware. It really isn't that difficult. Yes, there are some folks that are not that good at pvp. It's okay. However, you should practice outside of pvp so you don't negatively impact the team. By practice, I mean setting up keybinds, trying different combinations, understand your skills and skill tree, and what rotations play each skill off each other for maximum damage, healing, etc.
Please people. Stop complaining about non-existent bias and everything else. The truth is you want all the glory of crossing that goal line. Nevermind that you can get as much glory by stopping the enemy from scoring, too. I've seen my score, medals, objectives equal on defensive priority as I have on offensive priority. Everyone on the team plays a part. Learn yours and accept it and you will feel much better!
P.S. I do agree you should be able to queue for certain WZ's as everyone does have favorites for different reasons and there should be a couple more WZ's. Also, servers should be merged and cross-server pvp should be implemented more for the fact there will be less concern with what WZ you get put into if you aren't waiting 10-30 minutes on average to actually get INTO a WZ.
