Have anyone done the numbers to see how they compare? mainly thinking of kalla spirits vs hammers for condi rev. The spirits needs a lot more work to be effective, and you may get unlucky and having to deal with no path issues. Im myself on the fence about the spirits, i concede they have uses. But possibly no path issues, having to click a lot more to put them down is irritating. Plus having to watch for them expiering so they can be reapplied. I know you can speed up casting them with a setting in options, but they may end up in funny places due to the -very hard- to see cursor having run off, or gotting lost in the spam on screen in larger groups.
I could also be interested in knowing how devastation fares vs renegade. Though for renegade, it would be mainly versus kalla's fervor as the renegade line only improves bleeding.
