As a thief, it doesn’t feel very fun to have to order two kits at the same time. Not only is it a very sudden inventory management crisis event, where you have to scramble to store/trash things before someone sees your mountain of contraband, but it also forces you to make an overly large mission-approach decision early on, as opposed to being afforded a more methodical approach of selecting 1 kit now, 1 later depending on how the game is playing out.
It’s a simple thing, but I think it would add a lot more flexibility and fun to the role.
