When Simurgh was added, MR cards were the highest rarity Event Specialist for Chest Events. Being an MR card, she got the highest bonus effect.

When Surtr was added. UR cards were the highest rarity Event Specialist for Chest Events. Being only an MR card, he got the second-highest bonus effect. Hecate got the 50%.

Basically, they balanced the percentages according to actual availability as well, not just the abstract rarity of the color of the cardborder. With the 3 months between Simurgh and Surtr, UR cards had become more accessible. Not quite to the point that MR cards were when Simurgh came out, but the transition was going to be made at some point anyway.

To be fair, it is also a way to make the players more likely to see the UR cards as the new MR cards, despite still being a little harder to come by. The natural escalation of any game in this genre.
