Dusted of my 5x 17's (pally, priest, 3 mages) after getting tired of Faerlina. I went into the Deadmines with all whites and pulled one mob at a time up to the first boss, then resetting. On the second try, I pulled the first boss and barely beat him, then wiped on the paths that spawn behind you. I reset, equipped some new greens, and made it all the way to the level 19's in the Goblin room. After wiping a few times I figured this was my limit. So I did the instance over and over a few times, equipping better gear before each run. The runs got faster and faster, each time, and now I could do it in about 10 minutes.
