Here are the option definitions from the Macroquest2 wiki for ranger. Once you do the /melee save in game you can edit your file for those options.
To go back to your issue, here's a response eqmule gave someone a few days ago. You may just need mq2nav and a mesh
Usemq2melee=1 is correct but make sure mq2melee is loaded
I don’t unload mq2melee. It was probably done by the other kiss version.
Also stickhow can be whatever no need for move back
U need mq2nav and a proper mesh loaded as well.
