So this past weekend, I was able to do full runs of LFR and kill Deathwing on 4 different toons. While I had a few groups that were a bit of a struggle, on a general basis, most of the groups were pretty decent.
On top of these 4 toons, I've got two more toons that are close to being geared enough to run LFR. Given that I've never before killed an end-boss during the actual patch for that boss, I've really enjoyed the LFR process.
One goal that I'm thinking about setting for myself is to kill Deathwing on all 10 of my level 85's before the expansion hits. This would be the most challenging on the warrior, who's gear is pretty bad at this point, but can be quickly supplemented with BoE JP gear from other toons, at least to get him to the point where he can start running the new Hour of Twilight instances.
I'd also like to switch the shaman from enhance to elemental given the gear drops that I've seen, but not sure how easy that would be to do.
