It's very easy for developers to introduce Blitz. All we have to do as community is to bother them long enough. People are finally starting to realize how good this game mode is able to satisfy their needs, which is a good thing, as it is something that can induce growth in the player-base.
Losing matches in Blitz-mode feels less frustrating compared to losing while playing ranked, as we quickly can engage ourselves in another match. A more casual approach towards match-making and deck creation is what we all can benefit from.
So once in a while, lets keep creating new posts, promoting the same topic, just to show them that we still care about the Blitz. Players unite.
