Hello.
I'll try to be brief. After patch 4.3.2 I encountered an issue I can only describe as what the topic title says, i.e. 'triggered disconnects'.

Now first of all I do not want to hear any BS about my ISP being bad, I've ran tracert and netstat and everything is as it should be, no packet losses whatsoever.

That DC issue happens in a very sudden way: like for example in a 5man after I use some ability and instantly get disconnected (the time between me using an ability and getting to title screen with "you've been disconnected from the server" is less than 2 seconds.
Also, I've been doing a questline in Twilight Highlands about Iso'rath, when I die from the blood of iso'rath as the quest "Devoured" requires, and afterwards I get revived by Thrall in the Maelstrom, I get a blunt disconnect every single time I get teleported to the Maelstrom, right after the loading screen. I've tried to die from the blood of iso'rath at least 8 times with every possible combination of: 1) turning off every addon 2) deleting cache, wtf and addon folder 3) repairing the install
The only thing I did not try is reinstalling the whole game, and I am more than sure that it won't be of any help, either, since my install is less than 2 weeks old and I haven't been using more than 5 add-ons.
I've had a similar issue while questing in Uldum, too: on a quest "The Great Escape" when I stepped on a certain place of a deck of one of the ships the sailors are on, I've had a disconnect. I've tried it 4 times at least, and every time I step on that place I have a dc. The "workaround" was just to mount up and fly from the other angle.

This is not a problem related to my connection, that I am 100% positive, since I never have any latency problems, and especially not when the DC is approaching, like you were having a perfect playtime, you do your sinister strike routine and then bam! after another keypress you're on a title screen.

I understand that some players are having the same problem as I do, so please, say that you will look into this issue.
Thank you and sorry that I could not be brief enough, I'll provide any info as requested if it'll be of any help.
