It took them >1 year to fix the bug in Ursena Kage and other similar heroes. It took them some time to fix Lady Loki. Did they explain why? Nope.
They fixed the Alfrike/Wu Kong fast enough. Why? Cos they want players to keep pulling for Alfrike, for rush war.
Unless it brings in more revenue, whatever is requested for will be considered lower priority. Perhaps if an XL whale writes in asking for this or that improvement, it may just happen fast enough.
I wouldn’t bank on the game Customer Service or Devt Team paying much heed to player requests, unless those requests bring in revenue.
If you are that unhappy, perhaps it’s time to move on.
