My modified Changeling combat system

Last week, I mentioned briefly that I had devised a system for combat that suited my idea of how combat should work. I suppose this week, it would be a good idea to share that with you. So I will.

Ok, so this is intended for use in Changeling. I'm sure it would work equally well in the other Storyteller System games, especially the 2nd edition original World of Darkness lines. But I have no doubt that it could also be adapted for other systems as well. As noted earlier, this is an amalgamation of the Storyteller System, GURPS, Exalted, and Blue Planet's Synergy System.

First step is to determine initiative. I sill like the old "Roll Wits + Alertness (difficulty 4)" idea, although you can just as easily use the Revised edition's "Add Dexterity + Wits + the result of 1d10" version. In the former situation, you'd subtract your result from 10, and in the latter, you'd subtract from 20. This gives you the number of the starting "tick." The GM will count from zero, and when he reaches your tick, your character takes his action. After you've completed your action, you add the "action speed" of the action you just took (like maybe a two for shooting a gum, or a 5 for swinging a battle-axe, or a 10 for climbing a tree, or so on... I haven't ever actually seen a list of the suggested action speeds from Exalted, so I'm just guessing here) to the tick you just acted on. This can be modified by your Wits, or Dexterity, or both, to indicate that some characters can move and react faster than others. Like maybe if you have a Wits + Dexterity of seven, you can subtract one from all Action speeds. Or something like that.
