Hello there. Over the past few years, we have made it significantly easier to obtain Reroll Tickets through a variety of small and larger updates. With content like Dungeons and the PvP Chests, active players now have far better access to Reroll Tickets without needing to spend all their Pokedollars or rely solely on boss rewards and other income sources.
Because of this, I recommend exploring and engaging with that content instead of relying entirely on Pokedollars.
We have also had many discussions about new types of Reroll Tickets and additional systems, some of which we have already implemented. These include IV-locked Reroll Ticket, Double-IV-Locked Reroll Ticket, IV-Swap Ticket, IV-Shuffle Ticket, and in the future, even a Hidden Power-Reroll Ticket.
But we consistently rejected the idea of Reroll Tickets that only reroll a single IV (or two), as they would just be too good. Therefore, I’m rejecting this suggestion.
