1 - Dont have a problem, maybe try in your preferences menu to set your queue time lower or higher.
2 - I got no lag worth mentioning, and it might be directly related to your first complaint.
3 - Didnt do it yet, so no comment
4 - Didnt notice mut yet, but im only lvl 25
5 - No need for brackets, this is a very good option that works great.
6 - AFK is too fast for me. Sometimes im buffing inside the start zone and miss the block to enter the warzone. If you miss it once you get thrown out.
7 - I didnt see any bug yet, can you explain some more about which bugs you encounter ?
