I just played 2 games today, on Normal I think. I lost them both, because I tried strats that simply didn't work out (proxy deep outpost push and no-exp, mass-trader eco model). The AI seems weaker early and mid game, probably because there are no more nukes (or I simply get used to it

). Its offense is spread out on several smaller strikes rather than a single massive assault and it sends in reinforcements directly which is very much human-like, I really liked it. It moves faster to late game and tier-3 units (Onyx and Tiamat units) but it manages them poorly - I took out a 6 Onyx+2 Tiamat force with just a few embars, Draconi and Wyverns! (and I really cheesed that part of the game). My suggestion is to add some low-tier units as support for the late-game forces, because even though very strong, lone high-tier group are extremely vulnerable to Draconi and their Lockdown (it's my unit-of-choice mid-game and the main support unit late-game). From what I know about AI scripting it is not an easy thing to do, because the AI just sends its units regardless of their movement speed, but I wanted to let you know.
I also like the new harassing bit. Even though essentially pointless, it adds up to the game's dynamics and makes you feel the pressure, so thumbs up

I noticed a minor string error - AI's Tiamat Redeemers are called Vindicators. (and I knew they were Redeemers from their attack).
One more thing - I do not know what may be the cause of this, but I noticed a difference between playing games as "Custom Game" and as self-hosted UDP. Basically, in "Custom Games" the AI was getting things much faster and outplayed me in no time (15-20 minutes or something). I think it may have to do with the game speed, as it affects triggers and such, but even when I set it to fastest I the game didn't feel the same as in a self-hosted UDP game (which is what I do now). Most probably it's just me and I overlooked something, but I wanted to share that.
I will try to check the other AI difficulties sometime soon
