Soooo...Dazzler is by far the best Solvarch counter in the game. It's not even close. The reason is that Dazzler's special attacks deal energy damage while Solvarch reflects 50% of the energy damage that his opponents deal back at them as physical damage, but Dazzler in turn reflects physical damage back as energy damage at 200% potency (if she's at sig 200). I think this cycle then loops and loops and loops, resulting in a single Sp1 from Dazzler that does almost 500K damage.
I didn't know this would happen or I wouldn't have tried to bait out a special attack from Solvarch for so long. I could have just thrown my Sp1as soon as I had it and was affected by one of his Kinetic Discharge passives.
