Basically what the title says - I'd like to be able to fill one of the slots on tougher missions to assist my worthless followers and increase (or decrease in case I'm the worthless one) the chances of success. Most of all making the missions actual content. They'd play out as scenarios, pitting you and your followers against trash mobs and the bosses mentioned in the oh-so-brief mission descriptions. Would be a good way to use the scenario tech too.
