We will know for sure on this by this time next week.
For now I will say it makes me a little happy that someone from Strat noticed this concern on the boards and spoke to it directly.
Thanks JohnG.
I might add that any feature used online has to be interpreted and presented to the game engine. So the fact we have reverse lineups online and similar feature in cdrom game does not mean it is literally the same as setting or not setting those in the cdrom game. This is a simple programming logic if lineup3 present use, else use lineup1. So I tend to trust JohnG and the programmers on this one.
If indeed we have JohnG's attention might ask one more question. Seems many are concerned this feature is being applied to existing teams. Is it too late to alter that so the feature is only used in future teams? Perhaps something similar to when bullpen v2 was introduced people could choose to use it or stick with old bullpen version on their existing teams.
Regardless of which way that answer falls I think it would promote some good will to see it at least spoken to even if that speaking is to say too late too difficult.
