I would lose brawler and bound armaments. This will open up 3 slots which I would replace with vigor, dark deal and rally.
Dark deal will help you out with your stamina problems. Rally is a really strong heal and is like the main reason to a run two handed weapon. You could do evasion too if you don't want rally. Streak is really buggy right now but if they ever fix it then it'll worth slotting.
I would also remorph power bash to reverberating bash for the major defile debuff.
I've never really used onslaught but I would swap that out for overload for a third buff bar for stuff like retreating manuevers, caltrops, streak, rearming trap or other fun skills. Then put dawnbreaker on the two hand bar.
