Curious as to how youve chosen to define "flop"
for the last 14 days, across conquest, ranked conquest, arena, joust - the most played season 8 gods are (in order) (and the order does not change when you sort by conquest only btw)
Cliodhna (most played)
Gilgamesh
Charybdis
Morgan Le Fay
Tiamat (least played)
Atlas (Not released)
So she is getting more play right now than Tiamat and Morgan, which implies to me that shes not really a flop at all. Her win% is a little low, but at SPL shes been decently prioritized. There isnt really an easy way to measure all of a gods' metrics for one single "success" data point though, gods can often just excel at some things and struggle at others.
I'd agree that she did have a rough release due to bugs, and the specific community here on reddit seems to have certain feelings toward her - but in general she is holding popularity just as well as any new god would (although its a little early to tell)
