I reached the character limit back in Legion. I had like 35 max level characters and 15 other characters of varying levels. I had to start deleting lower level characters to make new ones, which really frustrated me.
I ended up caving in and paying for a second account around the end of last year, and it’s eased the character limit frustrations for me, but not everyone has the money to pay for a second account. Definitely think they should bump up the character limit to 75-100, especially considering the game’s had the same character limit since it was created 15 years ago. Time for a change in that, in my opinion.
