Yep. I was pretty shocked to have one-shot Turn 4 in duty finder with complete strangers after struggling with it back in October.
Ditto with Turn 1, though pugging T4 can still be hit or miss even with the echo. Biggest problem there being that, occasionally you get people that are set on using strategies that're either outright bad, put too much stress on X-Y or Z players, or are just unusual enough that people don't know how to execute them.
People that go in using the more or less standard strategy you see on most videos and such, tend not to have an issue these days.
