Alright, then. Considering that We already have a rogue (striker) and a wizard (controller), I made a defender, in this case, a Minotaur Battlemind--which is the psionic defender class.
I focused on Abilities that reduce the damage I take or which let me move where I need to be, so I can soak all the hits for you guys, since that'll sort of be my job.
I shouldn't have any trouble with MapTool, and I've made a token and attached it to a character file, in the hopes that it will make things go smoothly. Here's hoping.
And I'm off to bed, for now. If I'm not messing up the timezone conversion, I've only got 7 hours to sleep. Alarm clock it is.
