I've thought about this a lot, and I think it would be better if they scrapped 2015 and worked on 2014 as much as possible.
The logic behind this is based in the concept of ongoing permutations of the game benefiting from a polished ME that would be transported into 2016, with technology/program advances being implemented then.
If SI truly are "happy with their ME" and so don't think it needs working on, it concerns me that they will transport this bugged and frustrating ME directly into 2015 with minimum tweaks.
In short, I'd happily sacrifice 2015 if it meant 2014 got much better and we (as a fan group) were content that it would be transported into 2016.
