After looking over Skill Tricks I do agree with some here. Some of the skill tricks would've actually made great feats. The others were either already created as feats or are fine as skill tricks.
Here's what I think should've been or already are feats:
INTERACTION
Group Fake-Out
Never Outnumbered
Timely Misdirection
MANIPULATION
Conceal Spellcasting (I believe this was already done as a feat, can't remember where)
Easy Escape (already done as a feat called Clever Wrestling)
Hidden Blade (they have a feat called Flick of the Wrist that does this I believe)
Mosquito's Bite
Quick Escape
MENTAL
Magical Appraisal (there's a feat either in Complete Arcane or Complete Mage that does this already)
Spot the Weak Point (there's a feat in Draconomicon called that is similar to this, it ignores armor and natural armor bonuses called Deft Strike...though this trick is better as it's a touch attack)
MOVEMENT
Acrobatic Backstab (this would make a great feat!)
Back on Your Feet (this can be done with the Tumble skill if your check is high enough, I believe DC 35 or 40, from Oriental Adventures)
Escape Attack
Nimble Stand (same as Back on Your Feet, though that trick lets you stand as an immediate action so maybe it trumps this one?)
Twisted Charge (already done as two feats, Fleet of Foot and the psionic feat Psionic Charge)
Well, those are what I think would be good feats. The rest are fine as skill tricks.
So Mike McArtor, what exactly constitutes as a skill trick? The sidebar gives an idea, but as you can see some of these tricks make good, if not great, feats. Though the sidebar stated skill tricks really wouldn't make great feats because players would not use them as often. However, a good example, Acrobatic Backstab many characters would love to take advantage of constantly. Tumbling by a foe and next attack counts the target as flat-footed...heck, it'd be broken as a feat, heh. It'd make a good Epic Feat.
