I figured I would post this here just in case anyone is interested in seeing how my group does Twintania. It was the first time I streamed T5 last night ever, and we managed to oneshot her (usually 2-5 attempts before we down her, 6 kills total now). It is from SMN PoV. I'm not exactly the best, but I believe I parsed 290~ dps overall.

It's in 1080p if you have a good enough connection to load it.

The big, loud guy is Fencepost, our main tank/FC leader.
