Well, you can do pretty nice tricks with it. Full attack and retreat 10ft, opponent gets only one attack if he charges, then you get full attack and so on... It's very powerful if used right. Works well for archers as well since it lets you fire full attacks and opponent only gets one change to sunder or disarm your bow (which may still succeed, of course). And there are classes in OA that let you get +30 competence bonus on those athletic skills...
