The only important mechanic is , and ever was, Pheromones. All the other mechanics were nerfed, but without Pheromone coordination, this fight is still hell.
You really need 3 people who have two brain cells each (two to run the pheromone and one to follow). Sadly, this week none of the LFR groups I've been in have met that criterion, nor have I been able to find anyone in trade chat (low pop server).
Although it is possible for 1 person to run, this means the raid takes twice as much damage as it would with 2 people running , and LFR quality healers often can't cope with that. When I've tried to solo run pheromones I've always died fairly quickly.
My preferred style of nerf would be some behaviour change to Pheromones, leave everything else as it was originally. Say, max stack of 10, and have it possible to control who gets it even when idiots are running everywhere.
