If you're going to have LP, have LP for EVERYTHING!
LP for moving, LP for not moving, LP for picking things up, LP for putting things down, LP for time spent in game, LP for moving over minimap spaces that you haven't moved over in a while, LP for moving over spaces that you have been over lots, LP for talking to people, LP for adding Kin
Small amounts, all the time. It may give pretty much everyone the same bonus, but 1 - It'll get people the skills they want quicker so they'll feel less compelled to grind, and 2 - It'll make people feel less like trading and exploring are hurting their development (even though it still is, it's a psychological thing)
Personally I'd prefer you removed it.
