For executives and directors, I disagree completely. The shareholders are paying them to make and execute decisions that will grow the company (and share price) over a long period of time. The share-based compensation plan should reflect (and help align) that they are being paid to make long-term decisions.
Those are inherently "promise/award before the hard work is done" type of grants as I see it. (Why would I pay you more for a decision you've already made or work you already did, unless we're just talking about a modest spot bonus for a job well done?)
