I'll try to be as concise as I can.
I had almost 2 years away from the game. A LOT has changed. I just reached CP162 and tried taking the step-up to Veteran dungeons today and following my experiences I'm feeling a bit lost and underwhelmed.
Firstly, getting into a random group seems impossible because my CP160 is "too low". I've tried guild runs and I'm running out of magicka 3-4 times per boss fight even with potions. I'm using the Combat Metrics add-on and I presume the figure it shows in brackets in-game is (Your DPS/Total DPS of Group)? If so, my DPS in fights is averaging 8000-10000, which feels really really poor.
At the moment my gear looks like:
Head - Overwhelming Hat CP150 (+Magicka)
Shoulders - Valkyn Skoria's Epaulets CP160 (+Magicka)
Chest - Jerkin of the Scathing Mage CP150 (+Magicka)
Hand - Gloves of the Scathing Mage CP150 (+Magicka)
Waist - Sash of the Scathing Mage CP150 (+Magicka)
Legs - Magnus Breeches CP160 (+Magicka)
Feet - Shoes of the Scathing Mage CP150 (+Magicka)
Neck - Commodore's Medal CP150 (+Mag Regen)
Ring 1 - Ring of Willpower CP150 (+Mag Regen)
ring 2 - Ring of the Scathing Mage CP150 (+Flame Resistance)
Staff 1 - Magnus Inferno Staff CP150 (Absorb Magicka)
staff 2 - Magnus Lightning Staff CP140 (Weapon/Spell Damage)
I currently have 40 points in Magicka and 24 in health.
Unbuffed my stats are Magicka 26082. Magicka Recovery 1363. Max Health 13905. Spell Damage 1094. Spell Crit 59.8%. Spell Resist 10636.
Spell Bar 1 (Fire Staff) is - Haunting Curse/Force Pulse/C-Frags/Inner Light/Bound Aegis (Shooting Star Ultimate)
Spell Bar 2 (Lightning Staff) is - Liquid Lightning/Blockade of Storms/Mages Wrath/Inner Light/Bound Aegis (Energy Overload Ultimate)
Spell Bar 3 is - Boundless Storm/Power Surge/Hardened Ward/Dark Conversion/Bound Aegis
My rotation is normally Boundless Storm+Power Surge at the start. Liquid Lightning, then Blockade of Storms (keep both up when they expire). I then place a Curse (keeping it up when it explodes). I then activate C-Frag procs with Force Pulse in between. I try to do light attacks in between each cast however after having 2 years out of the game, this is something that I know I definitely need to work on.
So I ask you please for you help fellow sorcerers. I am used to to playing end-game stuff and being pretty good at it so I'm feeling really disillusioned at the moment for being so rubbish.
