Rune knight and Ranger
first why Ranger i think this would good job for it should be focus bleed effect and traps use hawk and crossbow would be good additions it add 4th range jobs give them a ranger hawk that come in with claws to add bleed effect also with the summoner lose it debuff this job could take some of those debuff up on it bolts
Rune knight there many way to do this job
persona i think it a job crave runes into a blade kind jobs it mage tank jobs with focus on tank use runes blades could handle of blade that might be interest rune knight focus have broke long sword with runes use as way create the blade and sword give rune effect and apply those rune to gear
