A couple tau rules explained

There were some questions about Tau rules that were in question when I played a couple of people. Here they are:

1. Saves from markerlights? You get none. You can't roll cover or armor on hits, only wounds.
2. Plasma Rifles overheating? They dont overheat because they take a hit to strength to gain safety.
3. Rapid Fire on full movement of crisis suits? They are relentless and jumppack infantry. They can rapid fire and still take full 12 inches movement.

I hope that clears things up alittle. I had to research alittle to find them out, and for the most part we have been playing them right.
