I've done tons and tons and tons of heroics, UK is probably the easiest. But I've never 5 boxed a heroic. I finally spent some time working out how best to do my healing, so I test drove the new keys to target each party member and throw a lesser healing wave on them and it worked very well. I only had 1 death the entire run, the DK ate a smash on the last boss. But I'm very happy to report success. Now to farm the hell out of it :_)
