Even with midfight dc's and constant latency issues throughout the raid for multiple people, we managed to finally get this done. The encounter itself was not that difficult but connection issues made sure we sweated over this.
Personally, it's the first 25 man raid I haven't lagged or disconnected in for 2 weeks. Was nice to return to a successful raid.
Server fought with us some, including have to stand around scratching our arses for 30 mins waiting for a soft reset when Deathwhisper bugged.
Then copped a server reset 15 seconds after we kill Saurfang, so no pretty screenie.
Possible achievement spam link here tomorrow.
First impressions are pretty good - instance is quite interesting, boss fights are good. Difficultly level feels better than Ulduar was - we wiped a couple of times learning trash and at least once on every boss. No "lolOneShot" on any of them this time, which was a pleasant change from the previous three tiers.
