I think it depends on the tier also, the wisdom needed per research.
In our tier (number 2), we also ran out of resources. Of course we don’t have alliance stronghold max, (we have just level 7, storing 100k), but alliance resource building is only good for having more/higher resource total at start. Of course none of us have max personal alchemist tower, but even if we had, we still would definitely run out of wisdom.
For us also wisdom are spend at such huge amounts, it’s nearly impossible to refill the alliance stock, even if we would have max personal alchemist tower. When more than 40% can be spend by a single research, it’s just too steep.
As soon as conquest starts, wisdom is spend with giant portions. Players can then do first donation and need to wait till next day. We can do 3-4 researches and then it’s over. Then we need to wait more than a day to refill the university to have enough wisdom to start next research.
After many have done their daily donation, the alliance university is not even close to being full again, it’s not even filled halfway. When that’s the situation, I think either the amount of wisdom needed to research is way too high or personal donations possible by members is too low.
