Swipe could also by reason by a high level JA for many reasons other than damage output. If it has enmity increase and is more of a taunt with elemental damage. That's one reason to make it not subjob level. Also the fact that it doesn't erase all of your runes can also be a potential reason to keep it above subjob level. We'll have to see when it comes out next week. I am hoping it has something else not explained because it looks really underwhelming and currently by description doesn't make any sense for helping to tank.

Accuracy Bonus makes sense and I'm glad they are adding it, it expands gear and food options for mitigating damage without sacrificing as much accuracy, especially on newer content which is just loaded with evasion.
