I have not read any feedback on this so I apologize if I repeat things already suggested.
1. Gwendolyn should run less often, once per month is fine but no more
2. Gwendolyn should not make it possible to grow completely through crowns without having to do any farming. To fix this: do not give out nobles, coins, nobles, coins day after day. Each monthly Gwendolyn (see 1 above) should have only 1 instance of Nobles or 1 instance of coins for the entire event.
do these 2 things and Gwendolyn will be much better for the community overall.
