This entire thing can be summarized easily.

If you're that unhappy, unsub. Either come back later when the queues are smaller, or be that upset at the situation that you don't come back.

Or stay subbed and either suffer through the queues and log-in server issues, or somehow alter your playtime to play during non-peak hours.

I sympathize with everyone suffering this and understand your frustrations. They are 100% valid. But when you remove the heated emotions from everything, those are your choices.

If you choose to unsub, sorry you feel that way, the game will be here if you want to come back.
If you choose to stay, then you'll just have to deal with what's going on until it calms down.
