extreme lagg in ToC since patch

[soniqboom]

after suffering horrendous lagg in ulduar 25 and thorim evade bugging last night in ulduar 25 my guild decided to head over to ToC and do 2 x 10 man groups to finish off the nights raiding so i swap over to my DK to tank for one of the groups.
All is fine as we are buffing up etc getting a constant 60 FPS, but as soon as we make the pull on the beast encounter my FPS pretty much hits 1-2 game is freezing like crazy and eventually in Disconnected..
tried 2-3 pulls before the guild replaced me which is understandable so i wait for 20 mins or so till they clear it, i then make a Onyxia 10 group which I tank with zero issues no lagg no FPS spikes constant 50-60 FPS all through the fight.

So I ask has anybody else suffered this issue with ToC since the patch??
I have read posts about ppl chain DC`ing in the thorim and beasts encounters and even a few guildies have suffered from this issue but I have never been affected by any issues untill the 3.2.2 patch..
any Idea`s?

First of all fps doesn't have anything to do with lag...
2nd You could have stated your server? Time? Did anyone else on the server experience it etc...
