I know some of my players wanted this last night in our DnD Next Game as a feat.
Grappling Master
You’re good with you hands, and even better at bending your opponents.
- Gain a +2 to all grapple attempts to escape, maintain, or pin an opponent
- When you have an opponent pinned, you may immediately do 1d8 +str damage. This counts as a blunt weapon attack that you may modify with other feats or class abilities
- You may grapple creatures that are up to two sizes larger then you.
Thoughts?
Throat Punch Games 
Can you convert this to PF?
pathfinder has a bunch of similar feats. DnD Next feats are much more powerful then pathfinder feats because you get much fewer feats in DnD Next.
