Though Ubisoft has mostly focused on packing in as many new operators as possible into the Rainbow Six Siege roster, more recently, they have been playing around with a few reworks too. As seen with Tachanka and Blackbeard, a rework essentially changes the way an operator plays, while still keeping their core identity and uniqueness intact. Reworks tend to happen when an operator is being largely forgotten about by the playerbase, whether it's due to their weak kit, or their ineffective gadget which simply doesn't suit the gameplay loop anymore.
