Given the overall state of new content in general, where we're only getting, realistically one decent episodes worth of content I'd rather they release a yearly proper expansion pack with gear designed to last the entire 12 months, along with 3 raids, 2 solos, 2 duos and 2 alerts Normal, Elite and Elite+ can all be properly staggered throughout the duration as well. Then the rest of the time can be spent on events, survival mode, save the universe and meaningful QOL improvements.
What would really be cool is having the party goers in the Halloween instance actually be dressed in costumes instead of their regular street clothes
