You might call it premature to review a season that's intended to be live for three more months, but I'm about 80% done with it myself (including my goals on the secondary servers) and I think that's good enough to pass judgement on it.
In a nutshell, that judgement is a resounding "meh", similar to last season, though for completely different reasons. I loved Season 6's stronghold focus (I still use the Copero stronghold a lot on all servers - even bought the matching utility bundle from the Cartel Market), but its story was disappointing and the grindy meta achievement infuriating, meaning the good and the bad kind of cancelled each other out, meaning that all things considered I felt kind of blah about it.
Season 7 had no such problems. There hasn't been anything particularly terrible about it... but unfortunately there hasn't been anything particularly great about it either. It's just been kinda boring in a way I honestly didn't expect.
When the season's theme was first announced, I thought the concept of tying it to an existing world event sounded interesting, and bringing back world bosses that had been removed from the game several years ago sounded like a good idea to me too. However, in practice the fact that there wasn't anything new going on kind of got me down after a while.
I had some fun unlocking bounty hunting achievements on the other servers, where I often hadn't touched Bounty Contract Week before, but on Darth Malgus I already got all those achievements about a decade ago, and there just wasn't anything left for me to chase after. Same thing with the DvL bosses - I know some guildies were happy to finally tick off the achievement to kill them all, but again, I already got that four years ago, and I had so many DvL tokens left over I didn't even really know what to do with them.
I can live with a season without any grand rewards (the white Loth kitten is cute but I don't feel a pet is on the same level as a companion or stronghold), I can live with a season without a story, but I need there to be something.
I even kind of missed the currency drops in a weird way, because at least finding a strange new currency among your loot drops gave you an indication that something was different, even if you weren't following the latest news about the game or paying attention to the seasons UI. This time there just wasn't anything going on in the open that made me feel like a season was actually happening, no gameplay that was different from usual, nor anything new and intriguing out to see in the world (I remember seeing one of the meditation shrines in Season 4 before I'd got to the point of knowing what they were for and they instantly grabbed my attention). It just felt like a whole lot of nothing special.
Even Season 1 felt like it had more of a "vibe" than this, and that had all those tedious daily objectives to kill insectoid mobs on different planets. I was not a fan of those at all, but at least "killing insectoids that you usually wouldn't care about" was a theme! This season's one-minute intro to provide a pretext for why killing two DvL bosses a week should count as "bounty hunting" just wasn't enough.
I did like that we had both a seasonal weekly objective that was easy to solo and one for groups every week, but that's kind of it in terms of things that stood out to me positively. More than anything, this season made me feel like the worst kind of jaded MMO veteran, simply because everything about it felt so much like "been there, done that".
If you had a really good time with this season, please do let me know in the comments! I'd love to hear how other people felt inspired to hunt bounties every week or found fighting the DvL bosses a really novel experience. However, for me it was all just a bit too old hat, and I really hope that the next season will actually have something new to offer for long-time players (even if seasons are inherently about replaying old content to some extent).
