Well, fair dubsman, what you are examining here is a fundamental disconnect between the mechanics and the internal consistency of the game world and the friction caused by it.
Because it's a game and because there needs to be a semblance of balance.. and also because these things are built on decades old assumptions about the way certain things should be done, the idea of grabbing a person, throwing them to the ground, sitting on them, and then punching the everloving fuck out of them, is just unheard of.
Realistically, all of those things could happen in a few seconds.
In a game like D&D, that action requires you to spend one turn engaging in a grapple (a full round action), and then once you maintain that grapple (which might take several rounds), you need another full round to bring them to the ground, then another round to begin attacking them.
Average rounds in games like D&D typically last about 6 to 10 seconds, so we're looking at 12-30 seconds just to pull off these maneuver, in D&D logic.. and it should take no less than 3 seconds.
In some cases, gaining the option to use such a maneuver effectively may even require a series of feats to use, which is just absurd when you think about it.. Big damned heroes who fight monsters for a living, but they can't just throw themselves shoulder-first at an enemy and knock them over for an old fashioned ground and pound.
The solution? Work with you GM and figure out a quick and easy solution for this to make it work in a more sensible way that doesn't force you to adhere to wonky game logic.
