My guild got started when a pug decided to attempt to fight our way to droks, several nights in a row. We almost made it through about halfway, I think. But with the AI update and bugs I'm betting its a bit tougher.
Here's the point to my anecdote: Has anybody attempted to fight through with Heroes yet? From beacons perch to droks, that is(not the other way around, as I think its easier). With their interrupt skills and a well meshed team build, it makes me wonder. Just curious.
But that's just me trying to keep you guys from being bored

I think the Drift is the toughest part, other than that, with lvl 20 heroes it's like hot knife through the butter.
better than wait for a runner these days it seems
