don't forget that if you use BT+BS and not use Boneshield than you also free up 1 more talent point. So it is not only the 2% dam from Boneshield compared to an average BS but you also have to count the bonus dps you get if you put that 1 talent points somewhere else
this discussion's gotten a little silly. i think people have explained what clark's post meant quite thoroughly. 1 min duration on boneshield is primarily a wash, and probably a very small DPS loss compared to if it were 5 min.
off the top of my head, there are really no talent points (that you wouldn't have taken anyway) that added to the 20rp and bloodstrike every minute are going to give you the DPS gain of boneshield, considering most talent points are <= 1% dps. not to mention the damage mitigation should you actually get hit. we went over this discussion a month ago in the old thread.
i think it's time to focus on epidemic and whether it's worth dropping. furthermore, if maybe there's a helpful way to go about testing things on the PTR when it's up. i do have confidence in the simulator but these discussions of latency settings, not to mention the whole GoDisease conversation, have certainly pointed out that it does indeed has its biases.
edit: haha, caught myself right as you posted. i'm not going to argue with you, it's a loss. it's just a loss of > .5% dps, and more annoying than anything else.
