TLDR: my new build based on what they changed in the previous patch is now ***, my dps is weak asf because I dont light weave, I'm excluded from 30% of content so wtf am I getting ESO+ for and how am i supposed to put up with continually rebuilding my pet sorc let alone my other 11 alt chars?
no idea what the fuss is about even more
Some Sorcs liked the dots and made a working build around that. Useless now ...
Just because you like to play a specific way doesn't mean there's aren't people out there who prefer a different playstyle ...

I am one such Sorc, a pet sorc (just the VF) in particular who made my way through the upheaval of Nerfmire, dropping the use of shields and adapted my playstyle to be not that great but okayish for most but not vet DLC or endgame trial content.
Then the last patch arrived and I decided to completely revisit my skills and playstyle and it was worth it!
This is the build:
Necropotence and Mothers Sorrow, Thief Mundus, Slimecraw/Iceheart/Skoria. Lightning staff bar: Dark conversion, boundless storm, wall of unstable elements, liquid lightning, VF, Shooting Star.
Inferno Staff: Crystal Fragments, Degeneration, Soul Splitting Trap, Deadric Prey, VF Summon Storm Atronach.
(Spell crit potion for major prophecy).
I've been doing content I wouldn't have considered before and contributing positively to groups as a confident, useful dps.
ICP on vet - it was still demanding of attention and being careful but I didn't feel like dead weight or a useless dps member, I even did some normal trials and was thrilled to finally be able to farm the BIS meta sets for my characters.
For a time it was glorious and fun but now it seems I've been pushed down into the mud again.
With DoTs being nerfed, I'm forced to either use spammables or light weaving, which I never excelled in and or go back to being the boring heavy staff attacking, pet sorc with weak barely noticeable AOE/DOT skills and low dps disqualifying me from playing or farming.
I will stick with ESO until I've gained as most achievements on my main pet sorc as I can (excluding those impossible for me to get) and have done most of the content but if these changes keep happening and light weaving, quick reflexes remain the only way to do 30% of the content without being carried then I'm going to find an MMORPG that doesn't rely on such mechanics.
P.S. "Major and Minor Ward have been discontinued." Are. You. F'ing. Kidding. Me? So my characters that are already glass canons, built for dps who have to rely on healers and tanks in group content that don't always serve their function particularly well are going to be weaker, more easily killed with lesser defences.
So um what play as a tank or healer or META BIS DPS who light weaves and has superb hand eye coordination and crystal clear focused attention or only play overland and normal 'easier' dungeons AKA City of Ash 1, Spindleclutch 1, Crypt of Hearts 1, Fungal Grotto 1 or simply GTFO?
Was going to list all the changes that mean I have to completely rebuild my pet sorc build and/or accept being a wet noodle dps such as
"Summon Unstable Familiar:
Reduced the damage of this ability and its morphs’ basic attack by approximately 17%.
Increased the cost of the special activate of this ability and the Volatile Familiar morph to 4500, up from 2808.
Increased the duration of the special activate to 10 seconds, up from 8.
The base cost of summoning these abilities has been streamlined to 3510."
"Lightning Splash:
Increased the base duration of this ability and its morphs to 10 seconds, up from 8.
Increased the base cost to 4950, up from 3024.
Reduced the damage per tick by approximately 33%."
"Destructive Touch: Decreased the damage per tick of this ability and the Destructive Reach morph by approximately 63%.
Wall of Elements:
Increased the base duration of this ability and its morphs to 10 seconds, up from 8.
Increased base cost to 4950, up from 3024.
Reduced the damage per tick by approximately 32%."

but just can't be bothered now - it seems like I've just been royally f'd over not to mention my other 11 alt characters who will all probably need reskilling/building and skill leveling up again not to mention new sets or different enchants.
I'm guessing too that some of the sets I have farmed/am farming for my alts have been rendered useless or not BIS now that new sets are here too.
I may add an additional post when I've discovered just how nerfed/broken/useless this and my other 11 char builds are now.
