Combat is not broken to be "fixed", it simply hasn't been programmed yet. Nor are the rules finalised.
But then, combat also needs to be (pretty much) the last thing programmed, because we need a game infrastructure in place before we allow people to run around blowing things up.
However, if you wish to join the rules or implementation (programming) teams, I suggest you contact those in charge of the relevant areas (email@example.com for rules, firstname.lastname@example.org for programming) and send them a resume of your skills/experience in the area including links to examples of your work if possible.
