I take long breaks, come back near the start of my MMR and don’t get many bonus stars. I came back this time because of splendiferous whizbang, and it really is 14-20 bots per 1 real player making me quit again. I don’t find fun in defeating bots to climb to a place where there’s no bots, blizz really needs to deal with the CN bots.
EDIT: Bot Ban Update–Late March 2024 - Community Discussion - Hearthstone Forums (blizzard.com)
This is even proof of my claim. 585k bot acounts banned this month.
