Played 25man at first, first and second try we got disconnected then third try we killed them. As for feedback, it seems like they were hitting really weak. After that we went for 25-heroic, didn't really get a good feel for it since the lag made the balls very hard to dodge. Considering the fact that they do oneshot almost every player if you get hit, and that they have quite a big splash, move rather fast and with the usual ptr-lag we were trying to figure out tactics to not be wiped by the balls, no luck though. Also, for heroic mode, you would have to have some good tactics for dealing with whichever one of the twins that shields herself since there's a lot of damage you have to do for a short amount of time. Knowing the timers will probably make preparations for that part of the fight a bit easier. As for actually doing all that damage without having a few players with the proper type of empowered buff or heroism/bloodlust, that will probably be a challenge.

Did 10men heroic yesterday. All players in 10/25 Ulduar hardmode gear. Definately a fun encounter, but killing it in the 7th or 8th try is a bit too fast ;) Was our 1st night/hour on the Val'kyrs.

I think it was a bit too easy. I did it 10man normal today with my guild. None of us knew tacs and we were all in naxx25/uld10 gear and we killed all the bosses in 3 or 4 tries.
