Server Class buffs

[Kriegstofu]

or instead some kind of buff similar to Full invasion 2: For Example:
Chosen Marksman Increase Accuracy of All T1-T4 Crossbowmen,
Aventurier Increase Melee Damage of  All T1-T4 Crossbowmen,
Pavise reduce Damage Taken of All T1-T4 Crossbowmen,
Repeater inrease Attack Speed of  All T1-T4 Crossbowmen,
Zwei increase Attack Dmg of All  All T1-T4 Infrantry

etc.

Now one could make the buff only for lower tiers or either also for t5 on hard/rag difficulty
