Also consider if you want to build around potential speed buffs in your party (assuming you aren't gun sub here). It's very common to have at least 2.5k from a bow or gunslinger buff, so you might like to drop a few speed points. You can always carry things like broth (speed drink), 10% speed emblem, speed tonic etc. for those few times you have no speed buffs. It's kind of annoying when you build speed around no buffs and then you get 5k speed in party and it's a complete waste.
