The gaps are now even larger, you are even less likely to land a Debuff cause your can't bypass Spell Pen, you Can't MHM cause even if you make it through their SR there is a pretty good chance they will save right off the bat or with in 4 seconds. Can't even Finger Archers anymore, just casters. You just lost about 10% of the damage your CL, Lightning bolt SLA and Ball Lightning because even with a 38, as well as while he was debuffed, you were having trouble getting past the saves on Horroth/Suulo and now it is even worse. Don't worry too much though, your capstone makes up for the damage lost then some! Oh wait, Capstone doesn't give 20% more damage total, curse you lieing description!
But hey I can heal myself now! AND I have 82 more HP!
Funny that you bring up how uber DPS they are, cause I have yet to see a pug take more than 1 sorc in a DPS slot, unless it is a semi-guild run or Abbot. People don't seem to realize just how much damage they lose when they get half the spells they cast saved for half because they still do damage, your not looking at exactly how much. Go fight a mob with evasion using only Spells with a Reflex Save or a troll using only Disintegrate and see just how many more casts it would take than to finger it or hit it with a Polar Ray, That is pretty much what it is like while DPSing a Raid boss who has much better saves than a normal mob. Getting even 1/4 your spells saved for half is a massive DPS decrease.
You say use spells with no saves then. Well the wizard only deals a little less over the same time frame and if he conserves even more by using things like Embers or Cove Dagger, His SP pool will go just as far as the Sorc's pool, the Boss's death.
