Does the HD AI adapt or use different strategies?

Why does it always seem to go for the same strat? I'm practicing my fast castle against the hardest AI and It always goes for a lame archer+spear+skirmisher+scouts feudal "rush", in which the winner is determined by me getting a second TC up (or not) before it can swarm me so that it sends wave after wave of weak military to die to said TC while I drop a castle on a hill behind its villagers and start spamming samurai and yasama towers

I just came back to the game after a long break and I remember the HD AI actually adapting to your strategy which was a big upgrade from conqueror's AI, but in this case the only thing it did was try to attack my castle with individual rams, wasting even more resources than with the rush.

I tried as goths too, and maps other than arabia and It went for a rush every single time.
