Eventually, and then only if you PvP a lot, +CON/-STR for more HP. Your damage, although much less than the summon, isn't worthless, so hold off on nerfing STR until you really need to.
I'd skip +MEN -- the mdef/mp boost is pretty small, plus your INT is still useful for the C5 skills -- Betray, Mass Surrender to Wind, and Windshackle. Not SO useful that I think you should go -MEN instead of -INT, but useful nonetheless.
