Missing out on Sweep sucks, but sacrifices must be made. If I were to change things I would grab Grenadier at 16, followed by Power Management, and then Armor Sloping, finishing off with Nimble. Still doable without, but Grenadier just is so useful it makes things much easier if you get it early, and Armor Sloping + Nimble combo is basically just their for extra movement points which really isn't all that necessary. I finished with Body Weight Training, but Sweep is probably better. It's just that at that point in the game, I wanted to get as much movement points as possible, and Body Weight Training basically lowers our armor penalty to 5-8% I believe. That means that you have 50+ Movement Points at level 30 without any Tabis or Striders. Using a 140+ quality bootspring, and you have over 90 movement points which is awesome.
