Not being of the whiny kind, and there's not many fights I hate, but already this fight is.... Honestly, I wonder who conceived it and thought this would be remotely interesting.
It's an obscure fight, and considering that's the best thing I can say about it, I guess that pretty much illustrates my opinion.
But I won't leave it at simple whine, let me actually try to put into words my difficulties with this fight. As I said, it's obscure. Everything is. It's chaos, and there's no way to put any order in it but to stumble and fumble your way through it and pray to the gods that your tank doesn't randomly get gibbed or that one of your dps is not suddenly standing half a yard to close to another add. And through all that, you really have no idea what is happening, like I have time to think about anima or anything at this point. I now remember in normal there was something chasing you, possibly this was also the case in heroic but if it was, and call me a bad player, I didn't have time to notice.
Anyway, going a bit more into details: it's really unclear what a safe distance is to 'tank' one golem from another and prevent you getting gibbed. Add to this the considerable damage adds do (lone or not), and pet classes are just highly favoured to not only reduce raid damage but to preserve mobility. Add to that that there's basically SO many adds going on and everyone has their own corner, it's just near impossible to keep any kind of oversight. I'm somewhat reminded of Conclave of Winds, where we'd jokingly ask "so how's group 1 doing?!" "group 1's doing fine, and how's group 2?!" Sure, it's not that bad, but considering there's about four million adds and a huge !@# boss (of which we're unsure if it's intended to spawn so soon at all), with tons of damage and deaths seeming completely random and untracable, most of us honestly had no idea what was going on most of the time.
Aside from that, as I mentioned, the damage is plain ridiculous, even if we were succeeding to do it in a seemingly correct way. The damage in no form or way matches what is said in journal, making deaths completely unpredictable, random, and the entire fight an excruciating and frustrating experience - BOTH on normal and now also on heroic. And honestly, if this stays like this, people will just stack hunters and warlocks (which is pretty much already a given if the damage output from lone adds stays this high) and depending on the enrage even four healers will be a requirement just to deal with the spike damage (like empress).
Now we haven't even been able to see the rest of the fight, but at this point I just wish I weren't a warlock so I would be sure I'd be sat the moment this goes live. For the first time, we just gave up. I just hope this boss lies in a VERY distant future in 5.2.
Apologies for the harsh criticism.
