Quagmire, a level 7 warlord, is free.
My other two character slots are also free.
One currently holds Ikni, a genasi swordmage that I never quite got into the way I wanted. She's level 4 (could be pushed to 5 pretty easy with DM credits), but I'm considering retiring her in favor of a striker. If a mid-level group were put together that was in need of a striker, I'd be willing to go that route. I have concepts in mind for a sorcerer and a barbarian.
Since I'm left with the higher level team, the available characters are Brenwar (6th level defender), Joy (4th level leader) and Halleck (4-6th level leader depending on DM credit usage). Another leader would likely be overkill, or perhaps overheal, and being 7th level would stretch the level gap a bit too much. A level 4-5 striker on the other hand would balance the party nicely, and we could start with the option of including another player in the future.
