Suggestion:

Some configurable options for buffing team mates, opposing teams, or other such options.

Some examples -
One team completes a task and all opposing teams receive a buff or random buff (which is configurable)
One team member completes a task and all other members receive a buff (can be set within a time of completing another task)
Teams that are behind, when completing a task, debuff the team in the lead (set in the config)

An option for buffs and debuffs would help to even the playing field, or atleast slow other teams down, for teams with more skilled or seasoned players.
