Smelly fruitman (Durian) debuffs pen, crit dmg, and atk power while also giving hp, crit res, and def. Aiolos heals, gives slight boost to AB, and atk power periodically. She gives crit res and adds crit rate. She also hurts enemy AB and removes buffs. On first glance, Duran looks like the obvious choice. Having said that, Aiolos does lots of little things that add up. For example, if the first 12 minutes of the match is in your front and midlines, Duran is doing nothing. Aiolos is adding to your backline's power as well as slowly increasing the your backline's AB (up to 80%). Once the match is in the backline, Duran helps keep your GK alive while Aiolos is more focused on pushing the ball out of the line. The question you need to consider is this- does your team have issues getting the ball out? Does your GK have significant issues surviving more than one shot? Some food for thought. --- I have a slight issue at the moment - I am wondering if using Grandeur would be best for my backline (Nikita, Butt-chan, and Jiho), partly because she adds to my crit res, partly because she has chain with Evylin and is in Shanti and Evylin's chains. If I do commit to Grandeur, then I am looking at Serestia or Shu if I opt for LG pick.
