Respect Banner Targeting

The concept of respecting another's gacha pulls by respecting their targeted limited banner. This includes not rolling on the said banner to keep the "believed" pool to be abundance ready for their picking.

Friend 1: A guildmate of mine was pulling for Nian, I didn't need her so I ignored the banner to avoid deprivation of the limited pool.
Friend 2: You do realize Respect Banner Targeting isn't real?
