Base atma doesn't even change stats, just ilevel. Animus is unattainable right now (can only do 4 books) and so imo t5 weapons still trump zodiack AT THIS MOMENT.
In the future zodiack still get better again but right now its not eeven close to the best. Animus stage is worse than weathered soldiery gear (at least for my monk) and high allagen is ilvl115, so yeah. (For monk I'm going for repaired soildery as BiS anyway) Hell, id even reckon that levi weapon is better then my atma as It is right now...
