Yeah, I'm in the same boat. I just recently got my Titan EX clear from a LS group, we did it with 7 people even because it was late at night and most of the players in the group knew the fight well. I was the odd man out who died twice, but atleast I didn't get knocked off the edge so I was able to get rezzed and see the fight all the way to the end. It was a real confidence booster.

Right now T5 is just a pain. I've watched the video 100 times, played in DF like crazy, and still can't even get to Twisters phase 90% of the time - and if the group happens to make it to twisters, its usually half wiped and not doable anyways. It's definitely lowering my confidence cause I can't tell if its me, bad groups or alittle bit of both. Like I do the divebomb phase exactly the way everyone else does (the Pit method), and its still 50/50, sometimes I survive without getting hit, other times I get knocked out 2 straight times into the flaming wall of death, and I did nothing different between the two. It's just frustrating. I've grown okay with the idea of never getting past T5.
