1) If you are not able to patch anything yet, could you at least create something like a to-do list of things that will definitely come in the future or balance changes that will take effect soon?
2) If you really want to rescue the game, please follow this advice:
Remove any game elements from the game that makes a player unable to move. Some obvious examples are the stun and the bind effect. You don't have to trust me, but you surely can trust the overwatch developers and millions of overwatch players. Their developers made the same mistake in the early days as well and quickly learned why it is bad to remove a player's ability to move, doesn't matter for how long. There is currently only one real stun effect in the entire game in overwatch, which only lasts for half of a second and is only available for one hero. As you can see, players find it extremely unsatisfying to not being able to move or do some sort of dodging. But it's not only unsatisfying for the player; it slows down the entire gameplay A LOT and in S4L this even has a much greater impact as in overwatch. You can observe this effect in OS (PS Stun, CS Stun) as well as in unlimited mode (bind). Please, for the sake of the game, follow this advice and make S4 League fast paced again.
