Zirath - Dragonborn Warlord for DnD4

So, after reading through the DnD-books, I decided to build myself a Warlord (something I've mentioned in some of my previous posts). For my race, I choose Dragonborn, since that's something I've (obviously) never played, and I wanted to see what they where about.

From what I can judge, he is a decent warrior, able to attack and deal out fair amount of damage himself. I guess that against a Fighter he will having some serious problem. However, already at 1st lvl he can give his allies increased maneuverability, speed and endurance. He has a couple of ways to make his allies fight just a little longer with some extra hit points.
