Well they finally responded on blog to affection problems and it look like good ideas to fix that (more gift drops: from pvp battles, pachinko and so on, refresh in shop every 8 hours and they will add legendary affection items. Oh and in the shop you will get better items depending on your lvl ... so on high lvl you will see rare or legendary affection items selling and at some time you will not see white stuff anymore) ... now we just need them to implement it asap
