Hey, I'm looking for peoples opinions about IS. Do you guys think it does enough damage to waste a global on? With 2300 SP raid buffed it ticks for about 900. Which is quite a bit for a dot but I feel like I'm losing dps by using a global for it. Even worse if IFF is about to come off all my dots usually are at the same stage, and reapplying 3 instant casts that obviously don't do damage direct damage seems to be a net loss in dps.
What are your opinions?
