Yeah, I've always found the pinning rules in D&D to take way too long, coming from a martial artist perspective. Two rounds at most is enough to take many down. If there's not a feat for that already, there ought to be one.
The Sage said:...You can grab someone and establish a hold
with one attack, but pinning an opponent is an option only
when you can make an attack and you already have a foe in
your grasp (see If You’re Grappling in Chapter 8 of the PH).
To grab and pin someone in one turn, you have to have at least
two attacks available that turn.
I actually play a trip fighter. Your class is nice, but i would never take it. Just too single focused.
I mean, the trip bonuses are great, but you probably will end died due to lack of manuversfeats that increase your chances to survive at the foe that resisted after your first 23 atks.
If I could, I would be this one.
