Hey guys,
I've been boosting my dps ever since the Tyrael nerf, and it's currently at 18k. With my current gear I can complete the Siegebreaker run in 25 minutes, which is pretty good. You can check one of my runs here:
http://www.youtube.com/watch?v=w_yi1k6X8fQThe gear requirement has gone up a lot, you actually need badass gear to do Act 3 now. I realize that a lot of you may now be unable to complete the run due to enrage timers, which sucks, but I think that we can work around that.
First, I suggest you guys try to play multiplayer. Since they also removed the increased damage from additional players, it is now viable to tank in a group. You may want to change a few skills, in particular Ground Stomp is great. Others you can try are Threatening Shout and Seismic Slam (Strength of Earth). Seismic slam is amazing against normal mobs but really struggles against elite packs, as they are immune to knockback. Also I found out the hard way that the little flowers in whimsyshire are immune as well.
Blizzard is also changing the loot tables soon, such that top tier loot will drop in Act 2. So being stuck there won't be the worth thing in the world!
Oh, yesterday I also did a full solo clear of the game s a sanity check. Starting at 5 stack Siegebreaker, I went down and killed Cydaea, Azmodan, then Iskatu, Rakanoth, Izual, and Diablo, rolling 5 stacks the whole way. It took me around 2 hours, but I did get 4 bosses worth of 5 stack loot so it was still good. In particular Cydaea and Azmodan are close to each other, so getting 5 stacks for them may be worthwhile. I will try this route again today.
