It was mentioned that tomestones will be obtainable through the Duty Roulette. Can we get an idea of how many tomestones and of what type will be awarded to high-level players that use this feature?

As a follow-up, do you feel the tomestone rewards will be sufficient enough to encourage players to use the Duty Roulette in the first place (rather than just sticking to more Wanderer's Palace and Amdapor Keep speed runs)?
