The above answers are accurate, though it really depends on your playstyle and what you are useful for. If you're just mumming around on RUN and soloing UNMs and stuff like I do, I did Vivacious pulse/Swipe/Swordplay first, with Runes and Vallation afterwards. Only recently I started getting invites as RUN, where Gambit and Vall would have been more handy.
