[PvK]

Not only does OA have a good protection rate and use organics, but it doesn't even cost very many organics. They also don't suffer from bypassing via phased weapons, or lowering via depleters, or destruction via shield-destroying weapons. They do suffer to shard cannons, though those are expensive and low-damage.

Actually, OA was pretty darn over-powerful before this, but only IF and WHEN it was used in small battles, especially one-on-one battles. It was quite possible for say a cruiser with OA to avoid all damage from an entire 30-turn engagement with a single other cruiser, or certainly long enough to destroy the other cruiser.

However, what usually happens is a larger battle with more ships and more concentrated fire, so very frequently, all of the organic armor on one ship can be destroyed in one turn (by fire from multiple enemy ships), in which case it doesn't get a chance to heal.
