I don't think they will increase any activity. Cartel fighters like the caps that have been here for years as they have proved to be balanced. Boat pushing terrible, you have no armor at all and are a sitting duck. Orca dropping can work but theres limited numbers of people who can effectively orca drop. Not to mention most gangs don't care enough to go up to north wongs, so why would they care to go to these new cartels.
Also, Ghost Hotel was a cap previously and was removed. It just promotes sitting in houses
