Recently I realised I had a lot of addons running at once, so many infact that I thinks its been causing my game to lag, disconnet or freeze. Addon control, bagon, bartender, nubcombobar, tongues and total rp2 (last 2 since I'm an rper). I disabled atlas loot, DBM except for when raiding, recount and omen, which seems to let me play smoother, so before I had around 10-11 running, now down to 6.
So how many do you have running at once? And do you get any problems with them.
