I don't understand why (most of the time actually) magicka builds are complaining about Shuffle so much. Everyone can slot Shuffle (only requires Unchained or a bit stamregen) while no stamina build can use Dampen Magicka, which is an insanely strong skill as well (would actually trade my Shuffle against a stam version of Dampen Magicka lol).
I used to think that PvP was a tragedy, but now I realize, it's a comedy.
