I know a lot of Limerick people would talk about moving it to an 8-team top tier, or even a 10/12 team top division with two groups but both of those options would be inferior to the current format. The 8-team top division would make the 2nd tier woeful and the other would just mean there are handy games for a lot of the top teams to go in 2nd gear. The current format is best and, as you say, if any change should be made it’s a playoff between 2nd in 1B & 5th in 1A.
Unless you’re the second choice keeper and want to make some impression. A late despairing dive is better optics than standing there with your thumb up your hole.
