I'm planning to run a 4e game and me and my group are new to it, so I'm making the characters for the players to save some time and confusion. I'm thinking of having a Paladin in the group that would fill a defender/secondary leader role, but I noticed that many of the Charisma based powers use the keyword implement rather then weapon. I have always envisioned paladins as holy warriors rather then priests, so a paladin mainly using a holy symbol rather then a weapon sounds dinky. Would it be okay to houserule it so they have weapon keyword instead? Or would it have some repercussions that I have missed?
