> As from laning to team fight, and item building.

I was disappointed to hear one of the devs say that item selection was hard-coded following a popular guide (don't think they communicated this before).

This is OK, because what matters the most is that it won. It was previously impossible to build hard-coded AIs that would even beat decent players, and now the AI has beaten some pro players (albeit not the best of the best); but it'll still be nice to see superior item buying strategies being learned.
