Corvus Belli have dropped two massive updates for Infinity this month. They've returned several factions that hadn't been given rules this edition into play, updated a lot of army lists to get some better balance, and updated some rules to make things clearer or less unbalanced to play against.
On top of this, there's a new tournament mission pack, where all the old missions have been replaced (only the most recent three were kept), and a bunch of new ones added. As someone who's taken a few months off the game, I'm feeling a little bit like the meme from Community where the guy walks in to chaos having just gone to fetch the pizzas.
My Shasvastii got caught in the blast as the vanilla Combined Army took a well deserved balance adjustment to Ikadrons. Their points moving to 11 and losing Flash Pulses is entirely fair, but they were helping prop up the quite weak Shasvastii. Some of the Shasvastii characters got some changes or some new profiles. Victor Messer is definitely better, and the Jayth / Gwailo fireteam gained a keyword to make getting the link bonus easier.
Combined Army, meanwhile, got a bit more of a thorough overhaul. Several Shasvastii and Next Wave profiles got banished to their own factions, cheap order profiles became a little harder to come by, and a few of the regularly taken big scary pieces got a bit of a rework that I think actually makes them a little better overall.
In the land of my other NA2 factions, Druze changes were negligible, Ikari gained a Tohaa profile (the Kiiutan Imposter), and Dahshat similarly only got a couple of minor profile changes due to them being shared with other factions.
In the land of Nomads, the biggest change is officially NA2 - Star Co, the mixed Nomad mercenary company, returned. They're fine. There's basically no changes or they'd mess up the Nomad balance. Meanwhile Nomads got basically no changes. A couple of new profiles that were lacking a bit of oomph got some slight changes, but that was about it.
The changes don't affect me a huge amount. I am loving them, though. In a lot of my factions I've got a couple of new or reworked profiles to play around with and see how they change how the faction works. That said, I'm likely to start pretty conservatively with some simple Direct Action missions and some models I mostly know as I try and remind myself how to play...
