I stick to my idea that all those changes will not bring any good.
Lineup changes make sense only in some cases (like for example if you have a half program for some rookie), otherwise you only affect the confidence of drivers, you give them even more pressure and sense of precariety, don't give them time or means to learn from mistakes.
Last but not least, I can't recall any swapping-lineup team winning anything in the last 10 years and I fear they could be more.

Also, I think that they have to do something with their car. It seems that it can be driven only from Neuville. I've never believed that Mikkelsen has became all of a sudden a mediocre driver. Paddon had his own problems for sure but he was a better driver before new i20. Also Loeb seems not much comfortable.
It would be ok if Neuville won championships but he isn't...
