Jan 26th 2011 4:47AM stop complaining about mend rotten flesh, it's not impossible to interrupt. we even got the achievement on heroic mode, the one that u get when u don't let him heal at any point. we did that in pug too. better alternative could be found, and I seriously think blizzard aren't good for balance issues anymore. removing abilities just for the sake of balance, like the shapeshifting mechanics which shows how much blizzard sucks.
