I'm going to
Right now it looks like if you have the right gear for Glad, and the wrong gear for Fury, you're okay to go Glad for single target in Mythic HFC. MAYBE some of the fights where multidotters shine ( something like Blast Furnace ) would be nice for us as well, since there will be a lot of spread out targets up for a long time, to allow thunderclap and deep wounds to do a lot of work for us. So I'm hopeful we see a few Glad's here an there. But in Heroic Difficulty, go ham. Glad is perfectly fine for Heroic.
Keep in Touch,
