Ok since the patch notes are pretty much straight made up and contain no real info about these set changes, I'll start a thread here to document whats been changed.
Magicka Furnance:
Nerfed:
Old:
10% mana when you are hit by a melee attack, 5 second cooldown,
New:
15% mana when you are hit by a melee attack, 30 second cooldown,
Yokeda (Raid heavy set):
Old:
Did something silly to (made you a statue once an hour.)
New:
No longer works at all.
Aether (Raid light set)
Old:
Lowered enemy armor and spell resistance -10%.
New:
Probably unchanged, but the description was change to be made unclear with no indicator of how much the debuff is.
Hundings Rage:
Old:
Increased weapon damage for weapon damage abilities by 3-24. Claimed to be a percentage, but was actually just a flat increase. Also bugged: Does not function on staves.
New:
No change in functionality, however description was updated to match what it actually gives. Still bugged for staves?
Healing Mage (Resto staff raid set)
OG OLD:
-100 enemy power that stand in your aoe heals. (bit brokenly OP)
Recently pre patch:
-8% enemy power that stands in your aoe heals. (An insane 92% nerf for most high level enemies, barely worth using now)
Post 1.2.3?
NERFED AGAIN to add 30 second cooldown? (So the notes say, this ones unconfirmed, have a friend with set, will confirm).
Worm Cult/Hercines/Ebon:
Old:
Increase stats for entire party. Max party size was 24, so up to 24.
New;
Massive nerf down to a maximum of 4. Seems to apply to 4 nearest members, pretty horribly annoying and massive nerf that was completely unwarranted. These set are ULTRA difficult to acquire, and thus should be powerful.
Hilariously, the medium set, which was completely garbage in the first place, was double nerfed. The stats lowered AND this target limit. lol devs have no idea about loot in this game.
Seducer:
Description change only. This always affected all 3 types of resources (stamina, magicka and ultimate costs)
Old:
Reduces cost of abilities by 3%. (Description says spells)
New:
Reduces costs of abilities by 3% (Corrected description).
More to come, add you findings..
