With the Motiv Trident coming, there is really no reason for Motiv to build a Jackal LE. Just give Jackal and Jackal Carnage owners waiting for the LE a Trident and be done with the whole mess.
If Motiv is somehow able to successfully negotiate with the USBC to get the Jackals reinstated, the people who have already exchanged their Jackals really get the short end of the stick. Since there was really no true heavy oil ball available, people got a new ball but not anything remotely like what they had. If it turns out they could have waited and kept their Jackals, that will really be frustrating for them.
