Literally their vagueness on their patch notes. If you look at any other eSport game, they will tell you actual percentages without making them ridiculous, what they did to make matchmaking “better,” and actually tell you everything they changed.
Ridiculous percentages: Why is there such a large nerf to an individual across multiple skills? Or why nerf heroes that do not require further nerfing for an aspect of that hero?
Matchmaking “better” : What do you mean? You say you are fixing matchmaking but do not actually say what exactly was changed.
Hidden changes: They have been changing legendaries behind the scenes and not saying when the changes were released. We need patch info on each gear specifically changed to become close to competitive.
The main thing is be detailed with patch notes. I know there are many other issues which can also aid this subject (stated in many other forum posts), however this is a great game and like many before me have said it has the potential.
I do not want to see this game crumble do to its own doing. I would like to see an eSports with this, but there is a long way to go (as to why I think it will not succeed).
