No I don’t remember that in Wrath and that loading screen business really wasn’t as disruptive to play in legion nor lasted as long from what I recall. Once you were in the game you could play.
Ion said months ago this was top priority in one of his interviews and that we should be putting in bug reports when it happens, server time, character, server and location. I have been doing that but when it keeps on happening it seems either they are unable or unwilling to fix this.
I am not buying another expansion if the servers are going to be so bad as this one.
