It might not be worth waiting til Geysers, actually. Say you have 1,000 blues. Moss Titans: 695,200 xp, 5,283k loss Geyser Titans: 783,200 xp, 8,145k loss To make up the extra xp, you'll need to gather and make 235 crimsons into swamp titans. That'll cost you a 572k loss, and will take you about 2.4 hours of work. Moss titans + Swamp titans: 783,200 xp, 5,855k loss, 2.4 extra hours. Geyser titans: 783,200 xp, 8,145k loss So using geysers will save 2.4 hours at the cost of 2290k. If you can make 950k an hour geysers are better. Plus if you wait til geysers, you'll have to make fewer swamp titans which are kind of expensive right now.
