I agree, dc casting is still very much alive, you just adapt the toon for eh or ee content, in ee I would prefer a proper dc Wiz to a Sharadi Sorc.

Sharadi casters are pretty straight forward, activate double rainbow and cast strong spells with the procs, (ones listed below), for the missiles depending on quest I tend to take all Meta’s off (as wiz u will prob want quicken) the added effects do enough damage at minimal sp, but this ofc depends on quest, I have seen Sharadi casters kill quite slow in the past and do not understand how this is the case, they might have feats activated and trying to conserve sp!

Magic Missile – 5 missiles cast fast, low sp
Chain Missiles – A must with groups such as in FOT, spam cast it, up there as best Sharadi spell.
Ice Storm – 2 procs, not bad
Force Missiles – cast if have the sp, is nice to use with mm on 1 mob
Pris Spray – V nice, should use
Meteor Swarm – Gr8 Proc Spell, I also tend to use this one maxxed out with caster feats, but watch the sp drain.

Relevant force potency item also handy for the above, would get if dont have.

I also twist in energy burst on my sorc when in Sharadi, faster way to kill/prep large group of mobs.

I dont really use Sharadi on my Wiz though, only on Sorc, if want a damage mode I tend to go draconic, still get ok dc for trash mobs then.

with my wiz I use the missile spells mentioned by legend, but I am mostly acid and cold specced. So i use acid rain and ice storm to chuck on groups of mobs, followed up with a few chain missiles. I am half covered with meteor storm too, but as legend says, if you use this too much it can be a real SP drain for a Wiz
