If at the start I could log in successfully 1 out of 3 times, now I can be lucky to get 1 log in in 10 crashes. Nevertheless after last maintenance issue returned and is furious now. I sighed with a relief and could swap between my 18 chars without any fear of getting crash and having to restart the game.
Besides after one of the maintenances (the one where servers were rebooted) issue disappeared completely. For those curious - I did try to disable all addons, it did not change anything. It was very bad at first, but I thought it just one of the hiccups of Greymoor launch (which it had a lot of). Since Greymoor launched I've encountered game stopping to respond sometimes after arriving at character selection screen.
