Umm, sorry, but the same wizard can cast a single empowered sorching ray, a 2nd level spell cast in a 4th level slot, for 84 points of damage. Let me repeat...a 4TH LEVEL SLOT for a 15th level caster. Heck, as an 8th level slot they can empower AND maximize it for ungodly amounts of damage, all as a touch attack. Any save or die spell (such as even the lowly tasha's hideous laughter) could do it better.
That's still far less damage than the character in my simple example will do on a single full attack. Throughout the battle. With no need to worry about SR or fire immunity.
Furthermore I fail to see how the option to lay down the smack with spells
in addition to dominating melee is a
downside. (!)

If you want to claim that a wizard is useless in melee, compare him with other melee characters.
(And scorching ray gives you a maximum of three rays, not four. +1 ray at level 7, +2 rays at level 11.)

Tell me again how this is a great idea to be trying to hit people with your sword using a high level spell to polymorph and then cast yet another spell to hit someone with a weapon that had yet another spell cast on it plus you had to borrow or buy a magic item that is otherwise useless to you plus you had to take a feat that is otherwise useless to you and you had to have prerequisites for that feat that are sub-optimal as well.
Where do I begin?
The sword is not "otherwise useless". Remove
wraithstrike and a well built melee wizard can
still beat the crap out of just about any fighter-type. If it
was "otherwise useless", that's beside the point since a persistent
wraithstrike can be in effect 24/7.
Power Attack is not "otherwise useless " at all - it's an excellent feat, especially for a character with lower BAB and a (potentially) high attack bonus.
Your argument seems to boil down to:
1. Wizards are useless in melee, even with
wraithstrike.
2. Because of [1], no wizard will make an effort to be good at melee.
3. Because of [2], go to [1].
Spot the flaw...

Seriously...if you are going to try and use this as a Gish example, it was a horrible example. With normal out of the box players handbook spells you can be doing SO much more damage, at range, as a touch attack, without any magic items, suboptimal stats, or additional spells cast on you to prepare for it, than that example. I'm sure someone can come up with a decent example to demonstrate an extremely limited but effective sub-tactic to make wraithstrike broken (like you can do with most spells), but that was not the example.
A 15th level wizard can easily do 12d6 + 196 damage every round (with
haste effect activated) with the basic setup I posted. Remind me - which "out of the box players handbook spell" can do that for me?
