I personally remember watching our stream, 'cause I can't raid, throughout the whole 7 days or so of progress, bar the last day 'cause I started having severe headaches and sinus inflamation caused by a broken tooth. I can ask Spite if he streamed the day they killed it if you want.

I don't know much about the fight, so judge for yourselves. All I know from the first 50ish or so pulls I was in when I was still playing is that we always killed the guy with bloods first, and that Slavik is an off-spec tank, 'cause our guild only has 2 actual tanks.
There's no logs for anything this week, not just Klaxxi I think. We don't have a guy dedicated to do WoL, it's just occasionally done by whoever can be bothered, which quite often can be no one.
And as for the gaining ranks part, compared to Ragnaros, or 1st 2 MoP tiers, ER dropped 20 ranks, or even more, so I'm quite sure BoP-ing a tank is not why we're at this "high" rank (not being top50 with 5d a week raiding is shameful imho) atm lol.
