What if Guardian either reworked or as a C2 or C3 attribute becomes a party buff where the Peltast that last casted it will take damage for the party members. kinda like Devotion skill of Crusader from Ragnarok or Reversed Guardian Saint of ToS cleric. Only the Peltast still take attack reduction, the damage reduction get better utility since the peltast is literally tanking for the entire party
tank players mentality isnt about dealing DPS but as natural Masochist they prefer taking damage for the party.
if not this can be added for a Peltast C4 class
