Which units would you like to replace/add?

Another standalone expansion? No, thank you. We keep churning out content, but there's no time to come up with a strategy for these units, and they want to change even more things! Necropolis in the 5th installment is almost the same as in all the previous ones (except for the 4th). The units are well-balanced, and asking for more would be too much. So everyone says that this race smells like cheating. I don't think they'll offer to weaken the units. And if we're going to gather material for the 6th installment of Heroes, I'd probably bring back the Death Knights... Sorry for the critical expression...
