I'm going to compare this to other systems to help explain the 'problem' as I see it.
In something like Exalted, you get stunt dice for bothering to flavor what you are doing. Getting two additional dice in a pool is a big deal (potentially more if you really go all out) so you're probably going to go out of your way to do at least a two dice stunt every attack. Even supernatural creatures can be remarkably fragile. Makes you appreciate every risk you take and every attack. You can potentially end Exalt versus Exalt fights in ONE well-placed attack.
Where are we at in the typical game of DND? A single round of combat is rarely decisive, and for all that effort of flavoring how cool your character is you roll under 10 anyway and beef it. This is going to repeat a lot, and even your successes are generally not the deciding blow. Yeah, you're putting way too much energy into nothing.
My recommendation? Let people do nonstandard actions without need for feats or skills. On one condition. They HAVE to sell it. Sell it hard. Then they can roll to do it as part of an attack. They succeed? Enemy has an appropriate status. Be more generous the more extra they go, but they have to SELL SELL SELL. The bigger a thing they want to cause? The more they got to put into the description. Rewards effort, but use is limited by it's nature.
