It does look like an interesting build. However, I was hoping to nab a ranged power for my inspiring warlord to do something cool all those times I end up having to chuck a javelin. Feel like I got the proverbial middle finger. If you are a charisma warlord, most of the powers are duds.
For the Skirmishing build, I really like Skirmishing Presence. But I generally have a "Mobility rules" outlook.
The archer captain feat seems pretty unimpressive, unless you have a dagger throwing rogue who likes to be a safe distance from the enemy. But they can spend their own feat.
Paint the Bull's Eye is nice if you have a ranger or if your Int/Wis is greater than your strength, otherwise, decent but not impressive. If it had been Str+1 vs AC, it would have been perfect.
I like Risky Shot. Plain, simple, when you don't know what else to do, you use Risky Shot. Not leader-like at all, but sometimes you don't need to lead, just need to take something down.
Race the Arrow is excellent, especially with a Barbarian or other charger in the group.
Inspiring Shot has a bard-like feel to it. Not my favorite. I sure hope the build didn't get stuck with one option for a daily (and I hope they didn't pick "more healing" as a theme for a skirmishing build).
Over all I like what I see, as expected there are some cherries, and pickles. If I had to voice one concern, I sure hope there are enough ranged options to choose from for this build, since they will not easily be able to dip into currently published warlord powers.
