When we made characters he wanted everyone to have stats roughly equal to each other.
All of us had stats bonuses equal to about +5 to +7. The reason behind this is that he wanted us moderately equal in power.
In the second session the Sorc has a 26 charisma that means his DC's are now start at 18 without even adding the spell level.
Right, but as long as everyone's getting about the same treasure, he's done what he set out to do (that is, make the players fairly even). He's not going back on his word. It's powerful, but it's not more powerful than the rest of the party. And it's fun being powerful, you did say everyone was pretty much having fun.
I guess what I am getting at, is a lot of people think 15-20th level D&D is like superheroes. Will with what we got we are now superheroes at 3rd level. There is nothing out there at our challenge rating that can affect us.
I guess I just think it would be better to have alot of minor magic items then a couple of big ones.
I mean sure it is fun at 3rd level to wield a +5 holy, fire bursting, undead bane, greater disrupting, keen, greatsword but that also gets old fast.
So you're not having fun because the DM isn't challenging the party, then? Just let him know. Say, even off-handedly, even in-character, "These peons can't even challenge us!" Tell him it seems all too easy. DM's generally don't need much incentive to ramp up the challenge, give him some.

It's not a problem with the DM not keeping his word, at least.
