Sultry is a really fun map though, really glad it's been added. The devs have been super open to feedback and have actively made lots of changes.
I think the attitude towards playing new maps actually comes from top players. If the top players can convince everyone else to pug that map, people will eventually get comfortable with it.
I've been around long enough to remember this happening with sunshine, where there were /just/ enough invite players pulling for it to be played (specifically pushing for it to be pugged), that it eventually grew to be a staple. This is what makes me think that this could realistically happen with any map that has a really active dev team. Sunshine ran like absolute dog shit too for the longest time, and we overcame it lol.
I haven't played entropy I don't think but at least give it a season. Scrim it a little bit, pug it a little bit. DM the devs or get in a discord call with them. I'm totally sick of voting granary in and out every other season. It's a stupid map and we can do better
