over the past month, Kael’thas has 2602 picks and 317 bans in Master League, meaning he is picked more than EIGHT times more than than he is banned. on top of that, he barely fits into the top 20 most bans heroes in Masters.
Meaning this isn’t an issue in skilled played.
Now that those facts are out of the way:
The majority of players means absolutely nothing when it comes to hero balance. if skilled players have no trouble, it means it’s on YOU to get better at the game. It’s not up to the devs to hold your hand and nerf everything you feel is to good due to your lower level of skill.
and a large chunk of those players are straight bad at the game. they’ll blame comp for their loss, meanwhile in the replay they spend 20 minutes afk laning and feeding. These aren’t the players whose advice you want to listen to when balancing the game.
This isn’t a valid criticism. It might be a reason for a ban (chromie was banned in master league pre-nerf due to being annoying) but it isn’t valid criticism for the devs to make changes to the hero when bad players are the problem.
