Your job is a "caster", which means it casts things and doesn't do physical attacks. Don't walk up to them and auto-attack them because that's not what a caster does. The auto-attacks are based on the Strength stat, which is not found on caster gear so it's pointless and auto-attacks are suspended while casting. The auto-attacks also require you to be in melee range which is not where a caster normally is.
