This is both where, as the enforcer, you have a huge advantage and also where you have a huge disadvantage. Because the enforcer is the melee weapons expert, you will be well versed in all melee weaponry and will be able to cause massive damage with your melee weapons. Counterbalancing this tera gold, the enforcer is completely helpless when held at bay.
To make the best of the situation, however, you will want to choose either one - or two-handed edged, one - or two-handed blunt, or piercing weaponry and attempt to stick with that for the rest of the game to conserve IPs as much as possible.
One thing to keep in mind is that two-handed blunt weapons will be harder to train with and that the enforcer does have nano programs that will increase your one-handed blunt weaponry skill.
As a result, taking up the one-handed blunt weaponry with multiple melee weapons skill can yield some quick and easy results. It is also easier to train in one-handed melee weapons simply because you start out with a meager skill in this area.
Another thing to remember is that by focusing on piercing weaponry you will be able to use both one- and two-handed weapons because, in the piercing weapons category, they both rely upon the same skill, so this will provide a wider choice of weaponry.
