Initiative Passes, Making Wired *slightly* less important? Options

[Eyeless Blond]

I've had an idea kicking around in my head for awhile on how to make variable initiative passes work in SR4. At the same time, I've also been hearing mumblings about how Wired reflexes and other initiative pass boosters are too powerful, or at least too ubiquitous, and how combats tend to be too short since everyone draws a gun and caps someone else inside of three seconds.

Here's what I have so far. Initiative is rolled as normal, and calculated based on Score + successes, as normal. You number of initiative passes are equal to the successes rolled divided by two, rounded down, minimum 0. If you have zero initiative passes, you are essentially out of that round of combat: you do act in the first pass, same as everyone else, but you cannot take an offensive action. You can enter full defense, dive for cover, run away, etc. but not move offensively.

Wired Reflexes and other initiative boosters allow characters to gain one pass per success on the initiative test, up to a maximum of the initiative booster rating. For instance, a character with Wired Reflexes 2 gains 2 initiative passes from his first two successes on the initiative test, but would require a total of 4 successes to gain a 3rd initiative pass.
