From a strict usability standpoint, we think the visuals for Exploding Palm can be a little difficult to interpret. It's hard to tell who's affected by the Bleed and who's being damaged by the resulting explosion. Our Visual Effects team has made some improvements in 1.0.4 which will make it easier for players to tell who's bleeding and who's getting damaged.
From a mechanics standpoint, the three-second Bleed can make the explosion hard to pull off, and the damage just doesn't seem enough to be worth the Spirit cost. To help with both of these issues, we’re increasing the duration of the Bleed to nine seconds as well as its damage per second, which should make it more likely that monsters you’ve touched with Exploding Palm will go boomwhen they die.
Current: 220% weapon damage over 3 seconds
1.0.4: 745% weapon damage over 9 seconds
(Don't worry, Impending Doom is also having its duration increased to 15 seconds.)
Just had to post this... one of my favorite skills to use pre-Inferno makes a comeback.
Don't know which skill to bump for it, or how it will play out effectively, if at all, with the way I like to play, but DAMN this is one of the things I was looking forward to with 1.0.4.
