Wik said:Not a huge fan. They remind me too much of Magic: the Gathering. While they do have uses, and I concede that point, I generally don't like how they always came up in play:
ME: Alright, so the ogre raises his club, and brings it down upon your...
PLAYER: No he doesn't. I use an immediate action to jump ten feet away.
ME: Okay... so he takes a few steps forward...
PLAYER: He can't. He's already made his move.
ME: *sighs dramatically*
See, that's the point. You as a DM are getting annoyed that the monster you run is being foiled. In these cases, the power in the game is placed back in the hands of the player, which is kind of neat. Players and DMs have to come up with a cadence of action because of all the immediates and swifts ("is that everything?" before moving on to the next player in initiative).
In your illustrated example, you've got a great cinematic moment, where a (stupid) ogre tries its simplistic best to smush a foe. But player-characters are special, and heroic. The hero nimbly jumps aside, leaving the ogre completely puzzled. It's a good thing too; that was looking to be a nasty hit!
Players doing spectacular things is a Good Thing.
And the last bit, where the player reminds you of the rules (can't move before and after another action), is every bit as valid as when you (no doubt) do it to them.
