The AI got a lot smarter on both sides IMO. On hard mode the enemy beams you to take away your PD track every time you fire. I watch the enemy's direction on radar as the missile travels towards them, and nearly every time they turn abeam, break the lock, then turn back into you. Against heaters (at least up to the H) they got evasion down damn well too, wait for it and pull HARD as that missile closes. I also noticed my teammates aren't getting shot down much at all. Last flight I got into a no-sh*t 8 minute stalemate between myself and wingman vs 2 Fishbeds, half the remnants of a 4-man flight. One of the Sparrows hit its mark, and so did one of my wingman's, none of our heaters hit and every other sparrow either missed or went stupid. Then it was just guns, trying to deny angles and cover the other wing. Finally won, but it was a lot harder than I recall WoE/V/SF to be.
