There is only one way to melee solo now: open with BP: Rage, and then stop attacking if you take hate.

If you think it is bad now, wait until you grab one of those melee magian staves only SMN could use effectively.

Other ideas:
-enmity merits
-enmity gear instead of accuracy/attack gear
swap haste headgear for pet: haste headgear

Basically you can't eliminate the problem, you can only lessen it.
