You sure about this? He has capped haste in equip so 25% haste+advencing is ~24% and victory 12.5% so 2x march + haste is 61.5% and 0.5*38.5=0.1925 so under the cap so it should be capped already no?
Thats also for marches w/o brd hands +2. With those hands NIN should be capped with 2x march, haste spell, capped haste in equip and just 45%DW?
