Well, to be fair, if the warlock is missing with their encounter power, they probably would have missed with any other power. In other words, if they rolled poorly, it doesn't matter what their power selection was, except that they might have expended an encounter or daily. Either way, they've used their standard action to essentially do nothing, so in my opinion that isn't a good argument for saying that it's not overpowered.
Also, any other class with a similar roll is going to miss and have 'wasted' their standard action as well, and if they were using an encounter power it's gone now. That doesn't change just because you're a warlock. I don't see why warlocks should be the only class that can keep trying their encounter powers - it sucks to miss with one, no matter who you are.
