General in halls of lightning can be cake or very very hard. If he goes battle stance, guarantee you that a DK will die in about 5-10secs based on how many attacks actually hit. If our heal is once every 30, ya it wont work. Beserker stance is great because he hits really fast, so all you do is drop Mark of Blood on him and you are full health for most of it. I dunno I got both his adds down (who heal him) and luckily he stayed defensive stance the whole time. However once I switched to him he went battle stance and my tank was taking damage so fast that 3 lifeblooms, rejuvenation, regrowth heal over time and spamming Healing Touch when I could.. didnt keep him alive. Now my tank isnt the greatest, he's only 79, but I figure that much healing I should be ok. Of course during this time he is Whirlwinding which east your slaves up and you might have to waste Rune tap to heal them when tank might be full. I imagine once they are all 80 and good stuff it will be cake. However on heroic, I bet this guy can be punishing for an all melee group.
