I have to say that I was sceptical at first with CA taking that challenge called the Wood elves. This faction is so unique that I wasn't sure how it could fit the Total War engine properly.
Wood elves are in TT a high-cost army that can't field as many units as other faction but have a good arsenal of elite units with specific roles that can be extremely efficient if used properly in battle and now with a few tweak and buff, mainly to the archers, they will be a real threat in the hand of the right player.
*Basic infantry feel just right. They can hold their ground against most light armoured units but may have some trouble while facing Heavy armoured units, but the faction has the tools to deal with them anyway.
*A good roster of monstrous units to help hold the line and cause fear.
*Awesome missiles units that can be customised to deal with differents situations.
*Master of ambush and can deal a massive amount of damage against a group unprepared and rout them in no time.
*Skill trees of the Lords are diversified enough to make 2 Lords feel completely differents with differents roles. Since it's harder to field 20 stack army, I prefer to field 3-4 army of 7-8 units that work together. Having a specific army with a specific role make the wood elves feel even more "elite" as they should be.
*Their weakness is their numbers. They always are outnumbered, but as long as they manage to not get surrounded, they will do just fine. This is why this faction requires a lot of micro compared to some others.
On the campaign, they can expand, but it feels like they also nailed the "isolationist" trait of the wood elves. They can slowly build a great economy with very few settlements. and steamrolling every faction to occupy them don't really help the wood elves since they will need more armies to defend a bigger territory that doesn't get them as much resource as they would need to.
Outpost is working as it should in my opinion. The main purpose of an outpost is to have a temporary base of operation in foreign territory and it work as intended.
I find it easier to invest more in few settlements that will be enough to maintain a few stack in the late game. Enough to be able to defend the forest and have the resources to field an expeditionary force that can help allies in need. This is exactly how I pictured the wood elf faction and I have to say that CA nailed this one.
