These Undead, former Scourge, didn't go on a wild mindless rampage, they regained their free will, becoming the Forsaken. The same should have happened to the rest of the remaining Scourge when Arthas died at the end of WotLK.
As for the Demons, that's not what I was referring to. We have known for a long time that their souls return to the Nether when killed, and slowly reform there, until they can take physical form again. What was new in WoD, was the retcon of there being no alternate reality demons. No alternate Archimonde or Kil'Jaeden. The Archimonde that died at end of WC3:RoC, was the same Archimonde that died at the Black Gate in HFC at the end of WoD. There are only 1 of each individual demon, and they can apparently travel freely between alternate realities. While "There must always be a LK" is my personal worst, this one had the by faaaaar biggest backlash from the community, of any lorechange, ever. I mean, it was only about 2 years ago, you can't have missed it.
No, just no. The Scourge was a hivemind, just like the Zerg in Starcraft. The whole point of these two factions is that they are so strong because they are controlled by an individual. For strategic and tactical purposes in a war, being a hivemind is simply "the best". Splintered groups of units would never ever come close to the efficiency of a large army controlled by a single person.
Think of it this way, let's use raiding as an example. What's the hardest part about raiding? Assuming you have a functional strategy and sufficient gear, the main problem is just waiting for that try when nobody makes a mistake. Now image if a single person had the mental and physical capacity to play 20 chars at the same time. Take any random guy from a top 50 guild, and he would get worldfirst, totally demolishing any of the top guild resistance. A real guild has to wait for 20 persons to play perfectly at the same time. He (the hivemind) only has to wait for 1 try where just 1 person plays perfectly.
There's a reason why hiveminds are always incredibly OP and dangerous in fantasy and scifi. It's basically godmode for waging any kind of war.
