I agree. The system seems to be set up to be as obnoxious as possible. Cynically, not having a predictable rotation would require players to log in weekly instead of waiting for their troop to come up in rotation. However, if this is actually being used as a player retention mechanism, it’s a terrible mechanism for it…
Crafting should have been the one safe haven from RNG. Instead, nope, it’s just one more dice roll after another.
