By that logic, we should just have 2 classes of champions: DPS units with 1 health and tank units with 0 damage. Units can be better designed by being less extreme. Nightmare and Doppelganger were so extreme that "battle RNG" was often the primary factor in whether or not you cleared the wave. If Nightmare is targetted last, you clear. If Nightmare is targetted early (even when you position it in the back), you leak everything. That's not good design. Just because Nightmare and Doppelganger received health buffs does not remove their identity as DPS units. Let's compare some units: Nightmare: 0.69 DPS/gold Zeus: 0.51 DPS/gold Berserker: 0.41 DPS/gold, 0.55 DPS/gold against bosses Mudman: 0.27 DPS/gold Nightmare is still far-and-away the premier melee single-target DPS unit in the game. Hope that clarifies our reasoning behind the changes.
