I've been in favor of bringing back leagues ever since they were removed. The removal of leagues hit people who could only afford a bronze level deck or a silver level deck, etc, really hard. They no longer had the "safe space" where they could advance their deck gradually. The main point of the removal of the leagues was that some people with maxed cards could not climb out of the lower leagues cause they did not know the meta there and did poorly which was very discouraging for them. Well, I'm sure some way could be found for people to skip the "ELO Hell" lower leagues are for them and play at the level they want to play at.
