Alright so it's widely known that many many people still struggle to get those top tier end game DPS parses, which many times comes from complex rotations or too many skills to track, which makes it really easy to make a mistake or two...or in some cases way too many mistakes to get those 100k+ parses. Well, if what you just read sounds familiar to you, give my sorcerer build a shot.

TLDR - this post aims to help people who struggle with DPS

Gear: https://postimg.cc/mthB47tN (if you don't have Perfected Bahsei, normal version of this set will do exactly the same job, if you don't have access to Bahsei at all, you can use Burning Spell weave, Scathing mage, Julianos or any other set that gives you Spell Damage as 5th bonus)
Race: Breton will give you best sustain and as this is incredibly sustain hungry build, you will experience a lot more Spell Symmetry usage on other races.
In case you don't like the idea of trading your HP for Magicka, you can slot Inner Light in place of Spell Symmetry and run 3 reduce cost glyphs on your jewelry, as crazy as it sounds, it doesn't affect your DPS nearly as much as you would think

Frontbar:
Spammable - Deadric Tomb (you can learn how to place it down in a way where atleast 2 out of 3 mines hit the target, which works even on targets with the smallest hitbox, like a human npc for example)
Sustain ability - Spell Symetry (Mages Guild ability - instant cast ability which provides 3000 magicka and reduces cost of your next magicka ability by 33% - use it in place of your spammable when you get under 10-15k magicka, whatever makes for more comfortable playstyle for you, eventually you can learn to use it even lower but to get the feel for the build, try it as advised)
Proc ability - Crystal Fragments proc (Use it as often as possible, it helps with sustain and is a minimal damage loss - compared to one Tomb cast)
Pet1 (Scamp pet - using this pet's special ability is optional)
Pet2 (Flying pet - Tormentor morph is more DPS so its better for group content, Matriarch morph is for arenas and solo play)
ULT - Shooting Star (has better aoe burst potential compared to Atronach, use this for trash packs and in a situation where boss has less than approx. 5% HP)

Backbar:
AOE DoT - Unstable Wall of Elements (make sure to keep 90%+ uptime on this, when paired with Maelstom Destro staff it provides significant DPS boost in a form of light attack buff)
Single target delayed burst - Daedric Prey (this morph of Curse passively buffs your pets and your ultimate damage - Atronach)
Minor force buff - Channeled Acceleration (Rearming Trap can be used instead, for situations where you get to play melee)
Pet1
Pet2
ULT - Greater Atronach (your primary ultimate)

Rotation: I believe it's pointless listing a whole rotation, you can see it on the video and whenever I see someone typing out a rotation in written form I have to chuckle, since it provides absolutely no substance anyways. The best way to see how it works is to try it. What I will say are some pointers to make your life as easy as possible, and it's already pretty easy, as you have only 3 skill that you use regularly.
- As an opener, always start with Channeled Acceleration - pet2(flying) - pet1(scamp) - and then you can start with rotation (Prey - LA - Wall of Elements - Bar swap - LA - Tomb > keep doing this until you need to recast Prey, then eventually Wall etc.)
- Do not forget to use Crystal Fragments when they proc, it will save you significant amount of resources, which can result in better DPS, since it gets you one ability cast further from using Spell Symmetry
- Don't be afraid the small damage loss when using Spell Symmetry, if you have Mages Guild on lvl.10 with last passive unlocked all the way, you will get a LA buff for 3 seconds, which will buff your next 2 light attacks by 40% (unlocking this passive will save you quite a bit of DPS)
- Don't get greedy in the execute phase, this build has no execute damage, other than passively from Bloodthirsty traits, so keep your Wall and Prey up and don't be afraid to use Spell Symmetry if you are low on resources, even if the boss is nearly dead, it can cost you 1-2 Tomb casts

PS: If you have any questions, feel free to ask, I will try to answer the best according to my abilities.
