A sample with just negative opinions. It doesn't look like a representative sample.
Of course you will find people to say its shit. You will find people to say gold is shit.
Fifa16, on the ball is on of the most satisfying footy game. You have a proper midfield play. 15 in comparison was a end to end galore. Passing is not easy, you have to think and to pass laterally. Dribbling is super fun and responsive. You don't need to use tricks to beat your opponent, simply play with change of tempo and the balance of your opponent. Collisions and their detection are in general great, also the ref detection. The cpu ai is challenging and plays one of the most patient play ou can find. Some time too patient but at least it is not all about verticallity.
Its main default are the lack of variations in the cpu tactics, teams end up playing often a bit similarity. The CPU can be OP with finishing in the last third. Errors are often punished by a goal. The bad angle the CPU players commit some time when defending (dda).
As for up to date patches, you have FIP3 with the 2019/2020 season plus the winter transfers plus all the fifa20 leagues including the libertadores, plus the Russian, the Turkish league. How about that for an updated content?
Also almost all players face from recent fifa have been converted but also all the new stadiums.
