Same here. Except for a tactical mistake by me when playing them. I would be undefeated using them. The HOA can be deadly and them when they get closer the bows are brutal. The Deathseekers rock!! ( Be afraid be very very afraid)
HOA rocks when you pull it off. I used to rely on them as an opening gambit and it works really well. However, there's always that bad LD roll that negates the attack, which after that, your opponent gets under your field of fire and just renders HOA ineffective. The bows still rock, though! I remember taking out an advancing unit of Firstborn Macemen with a barrage of arrow fire.
Best thing about Black Bloods is that some units never panic or lose morale. Even the lowly Swordsmen can tie up the best unit out there and still has a chance of coming out on top.
