I have troubles with my Epic Sorcerer, currently level 22. He is a drow Fire Sorcerer, with 2 Fvs levels
On his second life (first life was wizard), no Epic PastLife.
Worse, he has to develop his ED, so don't count too much on ED power, except from low level twists.
I often play solo because there aren't lot of lfg when i play, but i join group when it is possible. I play on EH

I would like some advises for my Epic Sorcerer. Especially on the following points of interest

1) Offense

In Heroic, my spells and SLA were great, but in Epic, monster have more and more HP, so it is less and less effective
Also my charm & finger of death start to be resisted often.
Worse, sometimes i don't even break SR on drow (but i have soon finished Motu so SR will be less a problem)

Wich spells do you advise to use in Epic (currenlty cycling between fire SLA, firewall, scorching ray. Or force & elec spell for fire immune monsters)

2) Defense

Currently wearing shield (i have the shield feat line) + blue dragonplate (ml14). Even with some spell failure, it give me decent PRR
Thanks to Cocoon i can now heal myself (and healing spring helps too)
Casting displacement for big fights helps a lot
Only drawback : 440 hp at level 22, not a lot, so lucky critical bring me down quickly

3) Epic Gear

Currently, i have epic Cloak of flame and epic bracers of air. I have some commendations so i could buy some Motu Items
Wich gear should i try to acquire

The goal is not to be optimal, but to be able to level up to 30 (Then i will either ETR back to 20 and redo 20-30 then ETR+TR), or ETR+TR directly
Any general advises for epic arcane spellcaster are welcome
