Guess we'll just have to agree to disagree. I don't see it as strong as other people make it out to be. Let me rephrase that slightly... It is strong, but you need to make very specific builds to take advantage of it, and you often compensate in other areas when doing so. Just like any combo. There was a time (and it possibly still holds true) that Tripping-builds were considered more powerful than other melee builds (grappling, pure damage, disarming/sundering).
Tripping builds are IMHO stronger than many other melee builds. But that's okay, because they require so many feats to be really excellent that you've "paid" in flexibility. Also, trippers suffer from MAD (multiple ability dependency) if they want to go the Combat Reflexes, keep-'em-down route, which is one of the stronger trip tricks.
There are also effective counters to tripping. A 1st level Psionic power
catfall (an otherwise weaker version of
feather fall) negates one trip per round at the cost of your Immediate action, being a Dwarf helps a lot, swimming can help, many larger critters are immune (based on your size), oozes are immune to it, etc. It's strong, but not universally applicable.
Wraithstrike is not super-broken (like IMHO 3.0e
haste was), that's for sure. IMHO it would be perfectly balanced by one of two things:
1/ Standard action to cast, gives you touch attacks all next round (like
true strike). You can Quicken it as a 6th level spell.
2/ Swift action to cast, affects ONE attack.
Neither of these would really hurt Wizards, but might make the average Gish think carefully before filling her spell slots with nothing but
wraithstrikes.

We certainly can agree to disagree. Each of us has his own game, after all.

But you seem smart and rational, and I'm not so fixated on being right that I will ignore good arguments, so I'd appreciate criticism of the following reasoning:
IMHO Psionics is pretty well balanced. There's a Psionic feat chain (requires BAB +5 and three feats total) which allows you to make a melee attack as a touch attack once per round. The BAB prereq means it's aimed at PsiGish characters. You must make a DC 20 Concentration check to recharge this ability.
Three feats and pre-reqs requiring at least 6th level character, for the effect of a 2nd level spell? Seems okay.
Now, I also like Tome of Battle. There's a 2nd level maneuver in there which allows you to make a single attack as a Touch attack. If you're a Warblade, you can do this every other round, attacking normally on the in-between rounds.
So, seen in that light, a single touch attack for the price of a 2nd level spell is a bit too weak.
The main abuse I've seen with
wraithstrike, though, is when someone uses a large number of attacks in a single round. Typically, with a form that has Multiattack to reduce its secondary natural attack penalties.
So... how about this:
Wraithstrike
Necromancy
Level: Assassin 3, Sorc/Wiz 2
Components:
V
Casting time: 1 swift action
Range: Personal
Target:
One weapon or natural attack
Duration: 1 round
You let out a sickly moan, blah blah blah...
For the duration, your chosen weapon or natural attack resolves attack rolls as touch attacks, not normal attacks.

It's still an excellent choice for a Monk-Gish, good for a two-handed Power Attack Gish, and terrible for a Totemist 3 / Binder 5 / Aberrant Feat using natural attack monkey.
Thoughts?
