Well, for once us pugging tanks are in the same seat as pugging dps. The queue for LFR is a nightmare. Half an hour is perfectly normal, and you can't count on seeing the first bosses.
At least the content looks faceroll enough to make the five man trolls seem like a hulking obstacle when they were released.
My guess is that we'll see queue times lower as the raiding tanks collect their 4PC bonus and leave LFR never to return. Finding healers, however, will remain troublesome.
The other, maybe minor, issue with LFR for the pugadin is that we really don't need that much of the gear there. While the 4PC bonus is a huge boost for a raiding guild, a pugadin simply won't run into situations al that often where the difference between raidwalling every second or every third minute matters at all.
One could argue that the bonus is good in the LFR, but to be honest, we're roflstomping all over it the same week it's released. Sure, we're pugging with proper raiders, but gear inflation will be absurd between 378 five man drops and a very generous pool of 397 VP gear. Add the occasional 384 LFR drops bound to find their way to pugging raiders and we should expect to see 25k+ dps from even the more, erhum, unskilled dps a month or so from now. Healers are likely to see a similar increase in output.
I fully expect tanks gearing for expertise and hit-rating to handle both the new five mans and LFR within a couple of months. Partially because an average ilevel 390:ish allows us to do so, but also because there's a lot of threat slapped onto out VP gear.
