The AI has changed a few times from harder -> easier. They changed Seekers, Fulings, and the aggression from enemies towards bases and structures. The changes were to the way they actually attacked and moved - not just numbers.

Adding better AI is something they already have. They just need to allow us to enable it server side. Bonus points if they added better AI going forward - granted it probably won't be (and shouldn't be) a priority with the other content coming.
