Hawk52: One thing I could do, and I just thought of this, is multiclass my Sorcerer into a Wizard. Since he's a Half-Elf, he takes no Multiclass Penalty (I think) and that'd open up more crafting abilities if not immediately then down the road. Kind of wish I'd thought of that sooner...
Jarmo: Don't do that! You'd likely end up with Sorcerer8/Wizard2, or maybe wizard 3. Barely (maybe) able to cast 2nd level spells. Much less effective than 10th level sorcerer.
Congrats on getting the rogue/druid up and running. Probably a bit weak character, but should be fine for opening/disarming everything and healing + fire support.
AC's seem to be in line of what I had near the end. Only... Mithral Plate, Moon-Ivy armor? Where'd you get those? Also, see if you can find an elven wooden shield for the druid, that steel one hinders his spellcasting, or doesn't, not sure of druid things really.
The monk is working out fine for you? Now (again) knowing what's to come, I'd guess he'll be just fine.
I think I bought both, but the Mithral might have been something I found doing NC stuff. The Moon-Ivy was in that exotic weapon store in Nulb. Not the best armor, but it has a huge dex modifier to it. For the Rogue with her +6 dex modifer, it works out well. I was walking around with an obscene amount of Platinum with nothing to spend it on, so I splurged.
I did that AC post and now I've gotten AC upgrades. Found a Ring of Protection +2, and just got the Hero's Shield from the Arena NC quest. Both the Monk & Paladin are walking around at 25 AC, and Fighter/Cleric at 23.
As for the Monk, I still go back and forth with him. He can now heal himself slightly, which is handy. He's not a front line attacker despite what the class would lead you to believe. His DMG and hit % are nowhere near the Paladin or Fighter/Cleric. He also can't keep aggro for anything, so he's not good for saving spell casters. But in a big battle, with 25 AC, you can plunk him in the middle and he'll do fine. His deflect/catch arrow class feats makes archery almost impossible on him, and he can dart around the battlefield never taking AoO due to his tumble skill and feats like Dodge you can pick up.
But if I were to play another game would I make a Monk? No, I don't think so. He's not useless, and can be exceptionally useful in situations, but if I had less party members it'd either be the Monk or Meleny I'd cut first. He doesn't bring much to the table that better classes haven't already.
