I got the 4e core books when they first came out. On browsing through them, I thought that a Dragonborn Warlord would be a fun combo to play. But D&D is not a game my group wants to play, so the books sat there, essentially untouched.
Fast forward a few years, and my son is reading my 4e books and talking about starting a new game for his friends with them. I do some research, and find that Essentials seems to be the new hotness, so I get him the Monster Vault because everyone says the Monster Manual in my core set is badly broken. I get him the Rules Compendium because the errata for the DMG is seven million pages long. And I get him the two "Heroes of..." books because that's the kind of dad I am.
So my son has started his game and it's going swimmingly and he assures me that Essentials is great and way better than the old(!) core 4e books he started with. I take a look at his collection to see what a Dragonborn Warlord looks like in Essentials...and there isn't one.
Where did it go? Was it eliminated because it was broken? Or boring? Or upopular?
What if I still want to play one? Can I use the Warlord from the PHB? Is there another "Heroes of..." book on the way with the Warlord in it?
