This has been brought up in the past by others (such Arrien) but since we now have a designated forum for balance changes, now seems a good time to bring up the topic again and consolidate those suggestions of the past.
Since Enforcers have an aptitude (read: perks, buffs, and light skill bars) for 6 different types of melee weapons, how about tweaking each type to be more suitable for a designated task then the other types?
The dIfferent types of gameplay an enforcer mainly is involved in are: PvP, Soloing, and Tanking.
Changes could be implemented in both the perklines, as well as many of the weapons in the form of procs.
Some suggested ideas:
2he/2hb might be orientated towards PvP. Give those weapons high max dmg and procs/perks in the lines would revolve around AAO and +dmg.
1he/1hb could be orientated towards Solo PvM, with high min dmg, good dps, and the procs/perks/WeaponProcs centered around AAD/heal/absorbs.
Melee Energy and Piercing might revolve around retaining aggro and tanking with procs/perks/weapon procs all adding taunts/AAD throughout the lines.
