Just a quick thought/suggestion but theres an obvious issue with balance in numbers for PvP. If Cryptic dont want to take the '1 minute wait' rule before starting each match perhaps it may be an idea that whoever presses the 'call for reinforcements' button faster gets their team beamed down. By this I mean BOFFs.
Sure they arnt as good as other players but then at least you have some help. Theres nothing worse than being 5v1. At least give that 1 person a chance to field 5v5 even if they arent as intelligent (negotiable).
In addition have the 'bots' take up temporary slots so that if someone else wants to join they take their place.
