Well, lets be realistic. No matter what stat additions are added to those weapons, those classes are rather underpowered. The various skills which a Soul Gladiator and Soul Linker bring to a PvP aspect are rather limited in a high rate server which has healing items allowed in PvP areas. I have different ideas like having their weapons give skills such as Cold/Fire Bolt and a heft Int/MATK boost(Soul Linker), since their other MATK based skills are unallowed in PvP (they are rather powerful if an enemy has GTB unequipped) and Bash and a decent ATK boost (Soul Gladiator). Taekwon seems OK, sort of like a wannabe Paladin with it's huge HP boost brought upon by it's rank, but these classes are really not that useful in their current state. I say we make more drastic changes to their weapons than just stat additions, but I'm not very experienced with them so I wouldn't know what EXACTLY to suggest.
