Thank goodness they came to their senses. I don't blame them for trying, but almost every team I've scrimmed with absolutely hates it. Even teams that roll with multiple of the same hero say its absolutely boring and doesn't make the game fun. Couple of people I know that were interested in the comp scene, but hated the zero hero limit didn't want to play competitively, but hopefully this will make them come back.
This change is a good change, and hopefully it stays like this, in my opinion.
