This means that if you're not forcing masters to spawn at all and you run say 50 maps, you might only see each master once or perhaps more or less based on your luck.
If this ends up being a complete duff on the player's end with just RNG being perceived as a bug, can I formally request that the spawn rate is look at? Or at least the accrual rate from map bosses.
All I can be absolutely sure of as regards myself and others is that it currently feels quite bad.
Yeah, I can't confirm that but it would definitely be worth raising the question.
