From some pretty in depth testing I feel that Nxt5 is superior for this patch than Nxt6. In a recent match in the premier league I tried Nxt6 in the first half and had 14 shots and only 2 on target with 65% Possession. Here is a screenshot of the end result having switched to Nxt5 for the second half. Although I didn't score in the second half, the performance was far more dynamic with lots more CCC created and shots on target as you can see.

In summary when I switched to Nxt5 I had 18 shots and 11 on target compared to 14 shots and 2 on target with Nxt6.
I will try this test again and report some more if it helps Guzzla.
