Spammable abilities are for potatoes. Slot Mage fury and degeneration/entropy. Use fury only to proc frags, entropy to empowered frags, then burst.
Until you meet a destro sorc that keeps you permanently on your shield bar because he applies way too much pressure.
Actually, dual wield is for potatoes. If you think anyone good is going to stand there and let you curse fury entropy frag them, youre dreaming. It's the most predictable and easily avoidable combo in the game.
In order to land the sorc combo to begin with, you must apply constant pressure. Youre not doing that spamming fury and entropy. Sorry.
