How would both instances of Martial Flexibility interaction?
1) Two pools of 3 + 1/2 lvl. Neither interacts at all, allowing 2 feat gains with 2 move actions?
2) The two pools, and levels stack, so a Brawler 10/War sighted 10 would be as effective as a Warsighted 20, no more, no less.
3) They are redundant, and only the highest level one continues to benefit you.
4) Other (Some combination I haven't thought of)
