Many of the complaints you read are valid.
You all initially release a kickboxing game and have spent the majority of the past year patching in somewhat accessible (yet often absolutely ridiculous (i.e. driving takedown from the center of the cage) MMA elements.
With the exception of APEX Legends, EA struggles to deliver on promises or meet expectations.
The post launch support was necessary and gave you an opportunity to address your mistakes/continue developing (for example.. Why was this game launched without post KO strikes? You already did that in UFC 1. I will never forget watching Dana White play UFC 1 and noticing that you could not deliver strikes immediately after a KO and was like "WHAT THE F*&k happened?".)
