He suggested that Sunsingers rarely get more than one kill with their supers. Based on my personal experience that's not true. I would consider that a proper rebuttal because those are my experiences. I believe I am entitled to that.
His video also suggested that while they are broken we should also not complain about them either. We should adapt(and I do agree, people should learn to adapt). Perhaps I didn't explain it well, but my interpretation of his video is that things are broken, don't complain about them, and if you don't like it play another game. Based on that, we should never have complained about things like Sunbreakers, Thorn, etc...that to me is silly.
I get it. He's tried of hearing the same conversation and if I had to guess so are you. That's fine. His answer is "It's broken, move on" Well then by that logic, we should have said, "Sunbreakers are broken, move on"
Edit: I also feel like I am coming off wrong. Please know that I am not trying to come off rude or suggest your opinion of his video is wrong in any way.
