Hello fellow players,

i am in the process of making a caster for end game play (at some point. I am currently PM, with PL's sorc, fvs and 2x wiz. I plan to TR a last time into another caster. I enjoy the playstyle of being able to CC, instakill, self-heal and do damage when it's appropriate. I enjoyed my time as a wf wiz, as a wf sorc and now a human pm for the second time(fvs not so much, since i mostly pug). I don't have MotU yet, and i didn't play it in beta.
So, im theorycrafting about my different choices (in no particular order):

1. H-elf sorc with pally dilly and scroll healing. I'd choose human in a heartbeat if i didnt think the extra saves mattered.
2. Human (or elf?) PM
3. WF AM
4. WF Sorc

Before MotU i was thinking of making a necro focused air savant (the fast movement and instakilling would be fun).
Now im not sure that would be such a good idea due to the spellpen requirements for instakilling. So my current
thinking is WF AM with necro focus and web sla. Spec him in ice or acid and force, and he would have something
for all situations. With good mana, insightful reflexes, toughness and quickened recon he would be very hard to kill.
Then again, PM would be just as nice, but with +1dc on all other schools. Except i hear that light damage is prevalent, that loads of mobs have deathward and so on.

So, to the questions (again, in no particular order):

1. How important are DC's in MotU? Could i get away with a WF air savant with necro focus on the toughest content? I understand this would require 3 Spellpen feats and loads of twists, but is it doable without adding another 2 fvs lives? I don't need to have no-fail instakill, a 75-80% chance would be enough. I think the reduced cooldowns and extra mana would make up for more saves (i could be wrong of course

2. How prevalent is light damage in MotU? I severly dislike being one-shot by divines who spam light spells.

3. How good is web SLA now? I would think there are a lot of mobs immune to it?

4. How good are the PM SLA's in MotU? I understand the AM Arcane bolts and whatnot are still pretty tame.

5. Are savants doing well, or are there tons of mobs immune to several elements (a bad game mechanic imo. Blanket immunities are bad, mkay?)

6. How important are saves in MotU? Im especially thinking of reflex, as a sorc would have very low ref saves compared to a wizard.

7. How viable is scroll healing for a h-elf sorc? I know from my wf sorc days that spamming quickened recons saved my shiny metal behind more times than i can remember (*cough* Enter the kobold on Elite *cough*. As a wiz with high reflex saves though, that wasn't so much of a problem).

8. What would you choose, and why?

I understand that there is an enhancement pass coming up "Soon", so i will level up and hold my decision until i see
what they come up with. In the mean time i would appreciate any and all input from experienced players.

Thank you for your time.
