So... Intimidate isn't really a combat skill. Once the initiative dice come out, the time to intimidate is over. Unless you want to spend an entire minute (10 combat rounds) to attempt it. So, basically, if you walk into a situation where you're likely to be attacked on sight, or where you have already initiated combat, intimidate isn't going to allow you to change a foe's attitude towards you.
But, it is going to remain a useful skill in non-combat situations. It will also remain useful in combat situations, as the Demoralize action makes clear. Adding a shaken status to your opponents, even if just for a round, can certainly come in handy. So, that's how intimidate should work (sorry for the earlier confusion), and how it will work in the future... if I can keep my rules straight.
