Here's some thoughts on the recent changes:
-I don't mind some of the points nerfs, some of them were pretty necessary, but with RetCad now at 3DP, we have almost the same number of total detachment options as we had in 10th edition (6 compared to 7, or 8 if you run all three 1DP detachments which, ya know, probably don't). That's a bummer, this edition was marketed as "anything goes, SO MANY OPTIONS!" And we simply do not have many options. We'll be good, we'll be fine, and we'll have good performance at competitive levels, but it's just not looking fun at all.
-Farsight down to 70 points is kind of funny. It's definitely a good buff to him, but him costing the same as a Strike Team underlines one of his core issues, which is that he's not as powerful as he should be. In lore he stands toe to toe with some of the Imperium's best duelists, and, well, still loses. But I think a lot of us Farsight enjoyers can agree that we love fielding him and like any points buffs, but would rather see a stronger, more impactful Farsight.
-Mont'ka switching to Priority Assets is kind of fine I guess, but it's a huge flavor loss. The Killing Blow should not win by doing actions in the center. Simple as that. As far as being "good", again, I'm sure it's fine, especially now that Stormsurges can action and shoot, but now a lot of our Mont'ka lists are going to look nearly identical to our 10th edition ones, with some more cheap units to do actions and a few good damage dealers. Just feels weird to win through actions with the Killing Blow. Womp womp ig.
-Kauyon switching to Recon... This one is kind of interesting. Thematically idk if it's better, but here's my issue with it: Kauyon+AAC was a really good combo that a lot of us were playing with. Now they're both at Recon, which further restricts our options. And we have so few options that any restriction of them has proportionally WAY more effect on us than nearly any other faction.
Idk. I've been trying really hard not to doom, and to stay positive, but like... Playing Tau just isn't very fun right now for me. I'm looking around the table at my buddies who are running really neat detachment combos, and really interesting lists, and I'm here kinda just playing the same old RetCad, only nerfed, and now nerfed again. All the combos I wanted to try are incompatible, and my favorite detachment (old AuxCad) is just not there anymore.
It's not all bad, I do really like Force Dispositions, but it sucks seeing how few options we have.
