Effective PvP Combat

**Description**
Nowadays PvP combats depends alot of latency and in order to have a good pvp we need to be effective and somehow create a system that doesn't only depends on wheter the player hitted or not. We should have in count variables like: Packet Loss, Latency, Variance.

The issue names no files, tests, or entry points. Start by locating the PvP combat and packet-handling code, then determine how packet loss, latency, and variance are currently represented; done would require an agreed design and tests showing combat is not determined only by whether a hit was received.
