Completely disappeared without a trace. And deserters, who should have been brought back from previous installments of Heroes.

We need to bring back the Ifrits! Psychic Elementals, lizards, gnolls, basilisks, magogs... we need to bring them all back! Remake: Pitfiends/Pitlords, devils/archdevils - because what are they now... not very demonic. Remake the zombies - they were cuter in 3, and if there's a fat zombie, let them copy the bloated butcher from Blood. Just look at the proportions... Remake the trintons into dendroids with a different appearance. Turn the Black Knights into Necropolis units with red eyes and black armor!
