Before this patch, I tried once before to solo Bloodlord. I did it as BM at the time. It was pretty tricky, and had to glitch it to where I'd be on a ledge next to the stairs, and make my gorilla tank Bloodlord and the raptor near the bottom of the stairs. It would have to be set up exactly right, to keep from getting myself teleported off the ledge and then feared all over the place, my pet dropping off its aggro, and getting whirlwinded.
I tried it last night as MM, and it definitely feels easier to solo. I took my same gorilla, cleared out the room, and didn't even bother with the "glitch". I MD'd to my pet, and sent a few multi-shots so my pet could get extra aggro on both. Having the MD glyph is just absolutely brilliant for soloing old content. You can MD to your pet all day long, and never worry about pulling off except for random aggro dumps. Mend Pet seems to heal for more than before, and it helps that both my pet and myself have more health now.
Next up was Thekal. Before this patch, it was pretty close to impossible to solo this as a hunter. My paladin had no trouble, both as prot and as ret, but my hunter just couldn't do it. It was an entirely different story last night. I cleared out the room of the trash, and then did a MD'd Multi-Shot pull. The same strategy for Bloodlord worked wonders here, except of course when my pet would get stunned and they'd turn on me. But then I'd just Disengage, get my 30% movement speed buff, and kite the trio around until my pet could tank them again. Again, endless Multi-Shot MD's to my pet, and Mend Pet every so often works wonderfully. Switching to focus fire on whichever one was further ahead in health, of course. Now I don't have Silencing Shot, but having it would make it even easier, to interrupt when you see the heal coming.
All in all, neither boss was really a cakewalk, in fact I died once to Bloodlord. But it was definitely fun and a great opportunity to get acquainted with the changes, along with a chance at a couple of rare mounts and building rep, and having some last minute fun in an old raid that will soon be gone forever. My paladin is done with the place except for farming for the tiger mount, and never really had a challenge in the whole place, but doing it again on the hunter is quite an experience! I highly suggest giving it a try. I'd be interested in hearing others' experiences and suggestions with soloing it or other content with this patch. I'm curious if it's possible to solo part of Kara and maybe even some MC.
Next reset, I may try it out as BM and see how different it feels. I haven't been BM since about level 77 or so, as that is what I leveled up as. I've been MM ever since, which is about a year now. With the ability to have way more pets than before, and some of the exotics getting pretty cool abilities, I may try it out strictly for soloing old content.
