Actually, that's not quite right. New units should be the main topic of discussion there (and this should be monitored), and here we're talking about the differences between new and old units, and preferences in choosing them.
Here are the units I choose:
Level 1: Bone Warriors (with the removal of mass archer resurrection, they are no longer relevant)
Level 2: Rotting Zombies (the advantage of 2 health is very important)
Level 3: Ghosts (mana drain is better than ammunition drain, in my opinion)
Level 4: Vampire Princes (ooo, stunning is terrifying)
Level 5: Half Archliches and Higher Liches (both shoot, and Higher Liches can cast spells when needed)
Level 6: Only Messengers (devastating touch is, in my opinion, the best skill in the game)
Level 7: Astral Dragons are better (but I don't build them at all because of the Liches).
