Had some epic matches against normal AI, and I'm impressed about it. AI seems to be stupid sometimes, but it can punch so heavily in your face, if you are not carefull or simply underestimate it. In one of matches Space Marine normal AI countered my Solaria drop by droping its Orbital Bombardment on her and I lost her, but I still won thanks to well placed and timed Orbital Borbardment. In another while fighting against Ork normal AI I was pushed to its walls, yet I was able to hold enough to summon Solaria on the field and win the match. I remember Etherium also having solid AI, I couldn't win against normal AI in this game. Grey Goo's normal AI also can hit you hard sometimes. I won't forget even about Company of Heroes 2's AI who sometimes made me hard work.
Overall I'm impressed that Relic made difficult AI, but hey, you can still win if you know what to do. I like do compstomps on AI, but I don't mind with some challenge on Normal.
Kudos ro you from me for this and this game, Relic. You had proven for this.
