I don't have great thumbs, had a surgery years ago and left hand isn't awesome. So I've been into MagDK heavy attack builds since 2015. I played a CC Tank for a long time in my PvP groups, but then CC became essentially worthless, so I started really focusing on the heavy attacks. I farmed the sets, hours in Vet Maelstrom back in the day, DA arena.. I always said if they ever get rid of Molten Armaments I'll probably quit and here we are.
Do realize how much GOLD I FARMED FOR ALL THESE SETS OVER THE YEARS that you totally not just nerf, but turn into something so different it's worthless.
Maelstrom Staffs
Elegant
Infallible Aether
Sargents
Noble Duelist
Undaunted Infiltrator
Undaunted Unweaver
Knight Slayer
I won't count things like Masters Staffs, Zaans, Torugs Pact, Heartland Conqueror etc.. event thought they were all for the same reason.
And now each of those sets looks like "If you hit someone with 19 light attacks you get 500 magika back! or some insignificant amount of damage you won't notice.! but don't worry in PvP you'll never hit someone with 5 light attacks in a row anyway"
You guys really blew it, I know your in denial... but you should have taken care of the dedicated players and not "new players who will be here for a few days"
