Changed how “Weapon Virtuosity” works: Each additional weapon used during the mission has the potential to award up to +1% bonus (depending on how balanced usage is w.r.t. the most-used weapon). A quadratic falloff is applied in order to boost nearly-balanced usages. Non-competitive missions receive +3% for starting with Moron and +25% for using Moron exclusively. (@Stardrone @RuLinh
