As @ThePirateKing said, those examples actually were buffed quite recently, in the release prior to the current one.
Just adding in the full list from that particular round of buffs:
Since the heroes suggested by the OP have already been buffed in the last couple of months, I’m going to close this thread.
If you want to recommend specific buffs to a hero that hasn’t been buffed recently, you can search for an existing thread in Ideas & Feature Requests, and create a new one if there isn’t one for that hero. Thanks!
