Better Initiative (3.5e Variant Rule)

The Problem
Not all ability scores are created equal, and nowhere is this more true than with Dexterity. The majority of skills rely on it, two defensive values (AC and Reflex saves) rely on it, and, most importantly for our purposes, so does initiative. Needless to say, initiative is a very important value on any character, as acting sooner in combat is very important to absolutely anyone. However, those who favour Dexterity get a significant advantage over those who don't. Practically, one's reactions in combat don't always depend on sheer speed or hand-eye co-ordination, but are also dependent on planning and observational abilities - which initiative should reflect.

Additionally to this, level does not get taken into account when it comes to initiative at all, which is a significant problem, as a 1st level rogue can potentially have a higher initiative bonus than a 20th level fighter, which is outrightly strange, given the experience in combat of the latter.

The Solution
When rolling for initiative, characters add one-half of their character level, rounding down, plus their choice of their Dexterity, Intelligence or Wisdom modifiers to the roll.
