Just to clarify the abyssal blades stats don't decrease as you use your troops. And that the Stingpoint is only better for people who just started. It doesn't take long for the abyssal blade to become stronger.
Another thing don't bring up hansels because 99.9% of the time they have war equipment and they won't the Stingpoint because they have stuff like the soulreaper and the nightbringer
We'll have you ever looked at your abyssal blade when your at half units. If you haven't it stays EXACTLY THR SAME
275 mil attack(not bonus to allies) = 27.5mil from abyssal blade. At 50% - 137 mil attack = 13.7 mil mil from abyssal blade. Just cuz it doesn't change on the equipment doesn't mean it's static.
AB gives 5% bonus to attack. At full gives 5% of full stats. At 50% gives 5% of 50%b This has been proven. Hansel have low attack stats so a static bonus is much better.
