The 3rd Rogue got two major features: Sneak Attack and Lots of Skills. It's the Lot's of Skills that get trampled all over by the wizard. Let's look at the
3.5 SRD Skill list for the class. For the record, a lot of this is theory crafting. Theory craft doesn't always apply one to one in actual play.
Charm Person (1st) and
Suggestion (2nd) covers most of the Cha / Social Skills
Knock (2nd)and
Open/Close (0th) can cover most of the door opening things you might require (Knock has a range of 100 ft + 10 ft per level, so you can be a good distance away from any possible trapped door).
Spider Climb (2nd),
Jump (1st),
Fly (3rd), and
Gaseous Form (3rd) can handle almost all of the movement based skills
Detect Thoughts (2nd) can cover sense motive
Invisibility (2nd) covers hide
Alter Self (2nd) and
Disguise Self (1st) covers Disguise
Silent Image (1st) gets you pretty close to forgery (assuming you can keep concentrating on the document at hand)
Comprehend Languages (1st) gets Decipher Script
Various Divination spells greatly help Search and Spot, though these are not great 1 to 1 matches
Wizards can already use magical devices, so that's covered
Prestidigitation (0th) covers Sleight of Hand
Wizards already have access to Craft, Knowledge, and Profession
Animate Rope (1st) will probably cover most usages of Use Rope
What skills does that leave us?
- Appraise (Int)
- Disable Device
- Listen (Wis)
- Move Silently (Dex)
- Perform (Cha)
Can a good DM overcome this? Absolutely. The problem isn't that these spells exist. It's that these spells can be easily accessed either through lots of spell slots and cheap, player produced scrolls and wands.
None of the spells listed are beyond 3rd level, most are 2nd or 1st. Scribing a 3rd level spell cast by a 5th level wizard cost 15 XP and 375 gold. A 2nd level spell cast by a 3rd level wizard: 6 XP and 150 gold.
