Not sure this is really the better solution. The reason my initial inclination is In this direction is because I would prefer something that encouraged further investment in the relevant stats/skills. On the surface I think something like this might be more likely to encourage investing? Maybe?
Further, while spamming the game is always against the rules, there seem to be some places int he game where repeating a command is largely expected - as has been mentioned elsewhere. I also know that, without knowing any better, some players/character have even taught other PCs to engage in command repetition to accomplish things in cases where it might not be intended.
Lastly, it's not always clear to players if a command involves a skill check. There are some places where stats/skills don't seem to mater at all. Often enough that I can understand someone assuming that something like this doesn't. How often to we see players surprised to learn that applying makeup is linked to skills/stats and possibly even object to that being the case?
