I have a level 5 Dragonborn Bravura warlord who is the only leader in my party. My build is focused around granting extra attacks and combat advantage (perfect for the dragon born with the dragon fear racial power).
One of the things that became apparent in our game last night was that I don't have any powers or abilities that grant extra saving throws or bonuses to any kind of save. We are about 2 weeks away from level 6 and I am looking at the feats and utility powers trying to find something to help my allies be able to save. This isn't a primary focus, but it would be helpful to the party.
