I'm just hoping that since they said they were going to increase myth gains in 2.28 and 2.3 that this is just the first and smaller increase of the two. Roulettes are nice for steady myth gain without a ton of time invested specifically into getting myth tomes, but I feel like some of the other methods that currently give tiny amounts of tomes could use a boost. Mostly just beastmen dailies and treasure maps. They both give myth in amounts that make you say, "Eh, at least it's something." Personally I think the ones that give soldiery are even worse since the amount is so low you're unlikely to shave another dungeon run off or anything because of them, unless you get several over the course of the week.
