With the changes to Shadowknight's being switched to STR for all things damage and no longer using INT, shouldn't Death March also be updated to give INT & STR? I am at work right now so I don't have the specific value, but I believe the ability gives ~160 INT right now and no STR.
It hasn't been changed at all. It appears (yes, I'm speculating) that the devs left it that way as more of a group buff for casters now, rather than being a self-buff. Still, the +55 dps and +55 casting speed help when ae'ing large groups of mobs, so it's still worthwhile as a self-buff also, IMO.
I agree that it is still effective, I was mostly meaning that it was one of the only spells that they did not change from INT only to INT & STR. Honestly, it would have been nice for them, knowing that it was designed for DPS, to give INT, STR & AGI. The flip side is for it to give INT & AGI for the DPS classes.
