Officially a few things has been added to the combat system in fifth edition... Including a nice way to handle mass combat. The new wound-system is a stroke of genius. ( Yes, it actually IS possible to take several scratches and not go down to heavy wounds with it nowadays. Love it. )

.... On the unoficial side, we run with a segment-system for Inititative. A initiative counting upwards from zero and with skill-level+stat determining a time in seconds for actions. Makes combat run in a new and rather interesting way and balances up the fencer with the knight somewhat.

Other house-rules includes hardness levels for cover and armour... as well as penetration levels for weapons. (( Yes, there WILL be explanations for those rules in the ruleset for anyone who wishes to use them. ))
