[Update #2]: Creative Assembly has begun teasing a major Total War: Warhammer announcement.
[Update]: The new beta update has brought in even more buffs for the Wood Elves.
Wood Elves were one of the very first DLCs released for Total War: Warhammer 1, and it really showed. Their campaign was a complete mess that required you to go for a massive empire instead of sticking with the theme and defending your forest, none of your outposts had garrisons that could withstand even the smallest of enemy forces, and you were also heavily disincentivized from using your entire roster due to Amber.
The Wood Elves desperately needed a rework, and I'm delighted to say that the recent The Twisted & The Twilight update has brought in just that! Instead of going for a massive, continent-spanning empire, the Wood Elves are now all about healing and maintaining a variety of magical forests.
Not only that, but in order to make the defense-focused playstyle more enjoyable there are now plenty of unique events where you get to cripple enemy invasions before they even emerge on the campaign map. Combine this with the removal of all army restrictions, and the Wood Elves of today are a significantly more polished and fun faction to play as.
Besides the massive Wood Elves rework, the update has also brought in a variety of improvements to some of the long-forgotten lords and factions. Even Helman Ghorst, the completely unremarkable Vampire Counts DLC lord, has received a nifty buff that lets his mortis engines and corpse carts summon hordes of zombies! You can check out all of the changes over at the official patch notes.
The final thing worth mentioning is that all of this has arrived alongside a brand new piece of DLC, the titular The Twisted & The Twilight. As the name would imply, the DLC brings with it the Sisters of Twilight as a brand new legendary lord for the Wood Elves, Throt the Unclean as a legendary lord for the Skaven, as well as a bunch of new units and mechanics for both factions to toy around with.
To learn a little bit more about all of this, as well as check out some user reviews, over at Steam. Have fun, and I'll leave you with the launch trailer:
