Thanks Lax,

I was sitting around 800ms last night with spikes to 2000ms , doing Stockades and preemptive healing my tank as i couldn't see his health.. I ended up giving up.

I have a 50Mb internet cable connection which was working fine, I am in Switzerland connecting to EU UK servers on a single connection I am normally on 300ms.

Can running multiple wow instances increase my ping ?

FPS on all screens seemed to stay to my settings of 15 on non active windows and 50-60 on main one.

Maybe the issue is not related to hardware then.
