Wait you get to hatches and liquid hells? That's basically a clear. Seriously... It took my team and myself quite a while to get each phase down good and then the transition to twisters.
Now we even have one that got hit by DBs 99% of the time(and he has issues due to lag since bad ISP and as far away as possible from the servers) not getting hit once...

Took us a few months with atleast once per week a 90 min session of training and learning(at times even 4 hours). It helps to get to know the people you are playing with,
how they will react, what can go wrong for each person and so on. Now atleast a couple of us have 5+ clears with the rest getting there as well. And we will be starting on t6 this friday.
Hell we even managed to carry someone at one point(and I do mean they were dead most of the fight).

Unlike the rest I'm not saying it's easy. I'm saying it takes effort, focus, coordination and will to do it.

It took me 4 sessions to clear titan ex... it took me probably a dozen sessions over 2 months to clear garuda ex and it took me one session to clear iffy ex(in DF no less).

Best you can do is start your own LS and invite people that you do stuff in PF that you see can handle themselves and invite them there. That way you will always have a decent pool of people to call upon for help.
