Mistake busbars ?
#3
Surely it is a total non-issue with *adequate* bus bars? 

What matters is the difference in resistance between the pathways to the different cells. I can't see there being a significant difference with plenty copper in the bars along the pack. Sure more is better, but even the manufacturing differences between your (all new) cells are going to be more significant. 
Nickel has a much higher resistance than copper, and some of the nickel strips being used are quite thin. There probably is the potential for such an effect with nickel strips, but not with a few square mm cross-section copper, and you have 30mm2...

As a counsel of perfection, certainly opposite ends, equalising the path through each cell is ideal. But not needed if your bus bar resistance is insignificant, 

The opposite ends design is less convenient for racking, but does have a safety advantage in keeping the terminals as far apart as possible!
