The best kind of grinding is the grinding that manages to be fun

I agree. Each player is different. Some want to do the most efficient/quick grinding, some like to add some variety, some want the tomes ASAP, some take it easier. Some don't want to throw a soldiery tome to the floor ever an don't do the high level roulette when they have capped soldiery tomes, etc.

If you like to grind via roulettes, I'd do the ones you like from the start of the week, and not wait until you have capped your soldiery tomes, you'll benefit more days from the non-expert roulettes bonus, and you'll throw less soldiery tomes to the floor.
