Ouch. Three people to a fireteam. My clanmates are going to have some massive competition between each other in that case.
OT: My fireteam will be [i]balanced.[/i] One Hunter for mid-range to long-range combat, a Titan to help us in dire situations (and for CQB), and a Warlock. The Warlock can do whatever Warlocks do. Throw magic bombs, I guess?
