I'd be up for making TRL season 30 island maps only.
Mainly because it simplifies things like playoffs, where for season 29, we'll now have to figure out what maps to play on before each match... but it also just makes it easier to compare ratings and other statistics between players, without first having to figure out what % of their rounds were not played on islands.
More personally though, I just don't think cavern T17 is anywhere near as interesting or varied as complex island map T17, making it both a worse representation of general skill at the whole of Worms, but also kinda boring and repetitive. I fear that if I had to play 1 island, 1 cave against all of my opponents, I'd lose most of the motivation to take part in a single scheme ladder (where half the time, I risk being stuck in a situation where I just want the round to be over asap, even though that's bad tactically). In an all-around league that supports 10+ different schemes however, I wouldn't mind playing it on cavern maps if that's what my opponent wanted to pick. Variety there would come from all the other schemes we could pick!
