Not at all.
The event was fun, the research is interesting and the rewards are exclusively for paying customers… except that it wasn’t exclusive, and we didn’t need to pay.
We didn’t pay for boosted shiny rates, as this wasn’t mentioned once and I am personally glad they weren’t boosted otherwise every Kanto shiny would have no trade value just like CD pokemon.
However, this non-event event is not adequate compensation for the “exclusivity” that we paid for and didn’t receive. I don’t feel that having a rerun or partial rerun of the event would be a good idea either, as the 12 hour event was fun but the week long event after was just dragging it out too long.
What they should be offering instead are free tickets to the next “exclusive event” valued at the same price for those who purchased tickets for the Kanto event. That, in my opinion, is adequate compensation… not a few common items
