Yeah, but look at the actual power of the spell: In 3rd Edition the scope of a wish spell is severely limited. In 2nd Edition, a wish could literally do anything (albeit with the risk of DM word-twisting).
Many of the things that a 3rd Edition wish spell can do (requiring 5000 XP) can actually be done with a 2nd Edition wish spell with no penalty at all. 2nd Edition PHB, pg. 197: "If it is used to alter reality with respect to damage sustained by a party, or to bring a dead creature to life, or to escape from a difficult situation by lifting the spellcaster (and his party) from one place to another, it will not cause the wizard any disability.".
Er, I think you need to reread the spell description again. The disability it refers to is the fact that any other use of the spell causes the caster to weaken (-3 to STR) and require 2d4 days of bed rest. The 5 year ageing feature happens NO MATTER WHAT. Teleporting the caster home would still cause the 5 year age increase. The spell in 3e is much easier on casters...
This is somewhat my fault. I meant to top stoneskin, but apparently my fingers had other ideas..
Now this is a spell that simply is vastly different that before. The 2e version wasn't powerful at all (HELLO DART SPECIALISTS - what else was a fighter going to use those excess WPN slots after he got one in Longsword?) while the 3rd edition version is useless as well (10 pts of damage reduction? Please....)
Neither spell was good IMO. Still, I'll actually give you this one but I'm still disputing your claim that 3e spells are more powerful even though the subsystems such as the initiative system and the save system made ALL spells much more effective than before. For example, geneally speaking all of the spells from levels 4 aon up are more powerful thanks to the loss of the initiative system and the loss of wpn speed vs casting time and the addition of the Concentration skill
Wands are not cheap. The XP cost if you're creating scrolls and wands for yourself actually becomes significant very quickly. (I've got a wizard in my current campaign who does it. It helps a lot... but it also means that he's already a full level behind the other PCs. That's a meaningful trade-off.)
I'm going to take a wild shot in the dark here and guess that your 3rd Edition campaigns got rid of the XP penalty for crafting magic items. I know that's popular, but it does have a rather huge impact on game balance.
Er, no. He doesn't stay a level behind the party because a lower level character needs less CP to progress than a higher level character and catches up very quickly. Your implication is that the wizard is stuck behind the party but if you do the math, you'll realize the wizard catches up very quickly.
