Right, these are just your first impressions, I get that. If the Quan player is full screen and you both have no stamina, you will not even get the opportunity to combo him before your stamina replenishes, so you don't need to worry about doing no damage anymore than you normally would from full screen, especially vs such a strong zoning character. Of course, Summoner needs to be significantly nerfed anyways. It's true that you would have the disadvantage in such a scenario, but that would just mean that Jacqui would need to be balanced with that fact in mind. It doesn't mean that this change is a bad idea, because I think I've given enough reasons why it's most likely a great change. And many characters in the game need plenty of stamina for combos or some aspect of their offense like run cancels or teleports that require stamina.
