According to our data Serqet has gone up in win%, but only slightly, and has risen in play count significantly. We don't usually take day1 data too seriously though as its a small sample size and getting more matches often has a significant impact on the numbers.
For transparency:
Serqet's performance for Normal Conquest only, level 30+ only
Before Rebalance (9.2 bonus 2 weeks of data)
win% - #116
playcount - #105
After Rebalance (9.3 1 day of data)
win% - #109
playcount - #56
(#1 being the best/most played god in the game, #119 being the worst/least popular)
We will continue to run much more detailed data analysis in a few days/weeks and will be open to making further adjustments if necessary.
One of our primary goals for this rebalance was to decrease Serqet's SPL pick priority from #1 in the support role, which is not reflected in these casual charts. Ideally she is still a SPL support consideration, while also not being the most prioritized support in the league.
EDIT - OP linked ranked and I showed normal - this is because 1 day of ranked data is WAY too small to draw any conclusions, especially if you account for only plat+. However, even with clearly sketchy data shes not dead last in ranked in 9.3 in our charts.
