These changes seem very massive in scale and I highly doubt it will all be complete by this year. The changes will most likely go into next year and maybe end at the end of 2017.
With that in mind, would you guys still want an AP4 at all? Or care if they reduced the number of heroes again? Would you rather have one year without heroes so that the team could completely focus on these changes and more?
I personally wouldn't mind if they at the very least only released 5 heroes next year (Spider-Woman included please) so that they could put the rest of their attention on delivering more core quality updates to the game.
