The dammage done to monsters that the amulet was giving is 15% which was changed from multiplicative to additive. This means that for the average player (who has other sources of additive damage such as minor berserk, damage from chapion points ..) this will lower our overall damage by about 5%.
We know beam builds are easier but they are no way near the top builds. It provided a way for mid skill players to be able to run group PvE content in a decent way withough being overpowered.
The amulet needs either a buff from 15% to 20% or it needs its penalty to Light and heavy attack damage to be halved from 99% to 50% (as at 99% you can still proc weapon enchants with no damage loss).
What I am most afraid is that without a buff to the amulet we might need to kick players from trials if they run a beam build as their damage will be even lower than before and it is just not worth it keeping them around.
But for trial finder groups: man, those groups will struggle with damage as at least half of the players there are beam builds and they will not be able to finish any vet content.
(for me its fine I will just go to anyother of my other classes: DK, or pure sorc or pure nightblade or purre templar build is fine as long as people would know how to light attack weave)
But as a lot of people run beam builds with Velothi, nerfing their core item would make a drop in player enjoyment and can lead to less player base down the road which none of us want for this game.
The Sorc class masteries are just bad right now, and really need to be buffed
Conservation of Energy
This is alright, but Dark Exchange already gives a lot of sustain, and as a pure Sorc, you'll likely run Crystal Shard as a DD, which is the main role to use the increased max resources
Font of Power
At 30k max resources, this is around 17% increased WSD, which at 7k WSD, is an extra 1.2k. Not awful, but not good enough to draw people back to pure Sorc
Static Reverberation
On a no-pet Sorc, this could be alright, but the lower chance based on the number of permanent pets just doesn't work. I can see the idea here, that the pets are always active, and hitting something with 3 different attacks at once (you, Familiar, Twilight) could be OP, but is it? The pets attack around once per second, so they'll only ever trigger one hit of Static out of 5 per pet, but they tank your chance of applying it based on simply existing. Pets aren't that powerful, but they represent such a massive cost, since they need to be slotted on both bars
Calculated Defense
The 3% WSD to the group is nice, but a 30% shield for 0.5 secs doesn't really do much. At 40k health, which is the average health for a tank, this is a 12k shield, but Conjured Ward is around 14k. I can see the appeal of applying the shield when casting any ability, so you don't need to spend the Magicka cost for Conjured Ward, but it's not that appealing
Sphere of Influence
The only ability in their class kit that gives allies shields is Daedric Refuge, which is awful to try to actually use to shield anyone, since healers tend to be behind the group, but Refuge would need them to be in the middle of the group, and for a DD, with 20k Max Health, it's capped at 3k shields anyway. Fragmented Shield from Earthern Heart has around 6k shields when around 30k Max Magicka, and caps at 31% of the targets Max Health, but the entire skill line is better for support
Lead From the Front (Dragonknight)
While this isn't a Sorc Class Mastery, it's still worth discussing here, since the Major Berserk on this could kill Sorcerer as a support class. Sorcerer has very little in the way of group utility.
In Dark Magic: Absorption Field (heal), Crystal Weapon (1k armour shred for 5 secs), Encase (Major Maim), Vibrant Shroud (same as Encase, plus heal), Daedic Refuge (shields), and Exploitation (Minor Prophecy)
In Daedric Summoning: Summon Storm Atronach (Major Berserk and synergy to 1 ally), Summon Twilight Matriarch (heal), and Regenerative Ward (Minor Intellect and Endurance)
In Storm Calling: Lightning Splash (synergy to 1 ally), and Power Surge (heal)
That's all the group utility Sorcs have in class skills, but basically everything has better options elsewhere. The only one that can't easily be replaced, and the main reason right now to run any Sorc skill line on a support, is the Major Berserk. If DKs can give everyone Major Berserk for 13 secs when they cast Standard of Might, it would remove any reason to use Daedric Summoning on a support, which would leave Sorcs as DDs only
