I'll start by saying I've played my StamSorc as my main (primarily PvP but also some PvE) for nearly two years now. StamSorc as it sits on live right now I feel is in a pretty good place overall in the games current meta, at least for PvP. It is far from the best Stam class, but is not nearly as under powered as a lot of people make the class out to be. I feel there just needs to be some slight tweaking and the class can be very close to on par with the top Stam classes. My two largest concerns are from the lack of applicable passives available to it along with lack of buffs/debuffs compared to other classes. When you combine these two categories StamSorc is severely lacking.
Lets look at all the Stam classes in ESO and compare what classes have passives that are and are not applicable to a STAMINA based characters. I'm primarily looking at this from PvP side of things in terms of what is "normal" to be slotted. However most of it is still applicable to PvE as well. Also the excuse of "Sorc isn't a Stam class" doesn't fly. All classes can be played as Stamina or Magicka. Plus in ESO lore there is a thing called a Battle Mage which is a perfect example of a StamSorc.
StamSorc: Dark Magic, Blood Magic is useless unless you're a negate StamSorc running the damage morph and Exploitation is only useful for group buffs. So 2 of the 4 passives here aren't really applicable. Daedric Summoning, Rebate & Expert Summoner is useless and Daedric Protection is almost useless since bar space is at a premium with the 3rd Overload bar being removed it is hard to justify Bound Armor or wasting an Ultimate slot on your bar for Atro can be hard to justify. However I will count it as an applicable passive.. (8/12 applicable, or 7/12 applicable if you don't have Bound Armor slotted)
StamDK: Every single DK passive can be applicable to a StamDK. (12/12 applicable)
StamBlade: Every passive in Assassination & Shadow is applicable to a Stamblade, and three of the four passives in Siphoning are up in the air depending whether or not a Stamblade is using Leeching Strikes/Siphoning Attacks or Power Extraction. (9/12 applicable but possibly 12/12 applicable)
Stamplar: Every passive in Aedric Spear is applicable to a Stamplar, In Dawn's Wrath, Enduring Rays and Illuminate aren't really applicable to a Stamplar, although Illuminate a group buff for your group members but for the sake of this I'll say it isn't applicable. In Restoring Light, all are applicable, but one could make the argument that Light Weaver really isn't applicable unless the Stamplar is running Remembrance back bar, so let's say it isn't applicable. (9/12 applicable but possibly 10/12 applicable)
Stamden: Animal Companions, Bound with nature is really the only non applicable passive in this line. Winters Embrace, Piercing Cold isn't that applicable to a Stamden however since Stamdens do use Permafrost a lot that 6% damage is a nice buff to that, so I'll call it applicable. Green Balance, since Stamdens run Soothing Spores a lot in PvP every passive here is applicable. (11/12 applicable passives).
Based on passives alone, StamSorc is clearly at the bottom, this wouldn't be such a large problem if they had a ton of Buffs/Debuffs in their tool kit. However this isn't the case and StamSorc has the least amount of Buffs/Debuffs in their tool kit. I think the best bang for the buck change for StamSorc is to make Bound Armaments apply a specific buff or debuff that is actually useful, possibly making your next light attack apply major fracture to the target OR when activated it gives Minor Brutality or possibly Minor Berserk. Not only would this give StamSorc access to another buff/debuff but it would also make justifying Bound Armaments to get the Daedric Protection passive worthwhile.
In terms of reworking the other class passives, I would be open to ideas but at this point any sort of useful passive would be welcomed.
Yes a class "spammable" would be nice. However I really don't think it would be necessary if the class passives and buffs/debuffs it had access to were tweaked.
