This is really the first edition in which grappling is awesome (and a viable choice). Part of this is because the rules are finally easy to remember and use and part of it is precisely because a grappled prone creature must escape (which an ally can assist, by the way) before it can stand up. This adds an exciting dynamic to any fight, changing things up from a mere trading of blows.
If the rule makes you want to use it as a player and makes the DM want to see the players use it, it is working as intended.
