Having settled into our new guild Resurrected on Khaz'goroth - a much better fit for us than the previous high-end guild on Proudmoore was - we have made quite a decent headway (9/10 and looking like Blackhand won't prove too difficult) into heroic Blackrock Foundry.
Unlike others, I hadn't really had any complaints about Highmaul. It's an interesting enough raid dungeon and the Mythic fights are extremely challenging for me. However, BRF is proving to be what Blackwing Lair was to Molten Core - a huge step up in fun and mechanics.
We are, of course, still going through mythic Highmaul, since we still haven't cleared it. With the gear jump from T17 2 and 4pc bonuses, we managed to get mythic Brackenspore without too much trouble.
I can see mythic Tectus being a little bit of a challenge - I cannot imagine having to deal with US latency on this fight - the first time I've actually felt that the drop in latency wasn't just a happy convenience but a bit more of a necessity.
As it is, the first few attempts I couldn't manage to get out from under the mountains before getting one-shot (I eventually realised I couldn't afford to even be a single step behind the person getting targeted, otherwise I wouldn't make it).
I'm also still finding it difficult to maximise my SV DPS - at first glance, I can't really see any major errors, but I'm significantly behind compared to the other hunters in execution. On the other hand, I'm finding the set bonuses for SV a lot better than the BM set bonuses, just because I find the BM procs a little too random to be useful.
I'm still hopeful that I can make a killing on mythic Tectus using BM beast cleave, but we'll have to see how that goes.... we'd actually need to survive past the first lot of motes before I can figure that one out! :P
