DCs in arenas/battlegrounds

Hello,
Has anyone experienced a lot of DCs lately in arenas/bgs? On my hunter during 2h playtime I got DCd from arenas 3-4 times and couple of times in battlegrounds on my mage/rogue also.
I believe that it has something to do with addon, but I got plenty of them so I do not want to try disabling them one by one. Has anyone experienced this lately and maybe has a solution?

P.S. They are the weird kind of DCs - I got a disconnect, but I can connect instantly back and continue the arena/bg match. Is this maybe some kind of anti-cheat that is troubling me?

Addons I got - OmniCC, ExtraCD, Bartender, Gladius, Necrotrack etc.
