from what im seeing , 6.2 will be the final patch for onslaught as it will i assume conclude the onslaught story with kira and scourge as per influencer words. that makes it, miles smaller compared to revan. and astronomically smaller compared to the expansion i will not name! also keep in mind for shadow of revan it had the prelude which was 4 flashpoints, korriban, tython, manaan, rakata prime, the actual expansion it has rishi yavin, and ziost + dead ziost, an operation, it introduced more warzones. onslaught had 2 small planets. a prelude was ossus so thats a small daily planet
then expansion release was a small daily planet, and a smaller daily planet and half of its story takes place on corellia as a flashpoint experience. one operation. then 6.1 added 3 minutes of odessen story, and maybe HOPEFULLY a flashpoint experience for the kira and scourge story. major changes was just gearing. so yes it is very small expansion. but is that really a bad thing?
also at shadow of revans hype, they added the biggest feature this game has ever recieved, strongholds
