I recorded my last 36 shard uses so you don't have to (and because probably no one from the team did before they said it's fixed).
All of those 36 shard uses had odds of between 45% and 58%. All of them were pretty much using the shard of same tier apart from 2-3 of them using the shard tier above for stage 2.
I would say (but this I can't confirm) that 2/3 odds were around 45-48% and 1/3 were around 55-58% or other.
In those 36 tries I managed to capture an Illuvial 12 times. Which is** ~33%**.
That means I failed to capture an Illuvial on 24/36 tries, or ~67%.
Those odds are much better than the ones recorded before the patch but it's pretty clear they are still broken.
I think it's only fair we get acknowledgment from the team that the odds are still broken and they're working on them as we speak (type).
