One more thing for the Attack buff - it’s really broken.
Here’s two screenshots from one video (can upload if you want), where normal attack damage is 400 - and 800+ after 20 seconds with same heroes and same status effects.
@Petri , there’s no answer on this mass-bug, kindly ask for your comment. At least mark it as a KNOWN ISSUE
While investigating, pls keep in mind the information in this post.
