Random hot takes, as of Conquest 16.
Game is much better balanced than Awakening. Spitting dual attacks, stat boosts, and pair guards really goes a long way in restoring the focus on tactics, rather than cranking out broken builds. The fact that enemies don't have same turn reinforcements also helps here.
Maps are incredible. Probably the best in the series from what I've seen so far. Some of the most challenging and interesting stuff I've seen. Dragon veins are awesome.
I miss Canto, though I understand why it would be seen as broken with pair attacks.
I also miss the ubiquity of shove and rescue, but it's nice they are still there in some regard. Lunge is pretty awesome too. Shove, Canto, and Rescue could lead to some insane tactics in the Tellius games, and that has been replaced by pairing formations, which is still cool. I think my ideal for the next game would be to return Canto, make shove and rescue a little more common, and slightly diminish the prevalence of pairing, so that all of the FE tactics can be used without any one of them being too broken.
There are too many supports still. I hate all of the support convos and unlimited supports is kinda dumb. Just go back to allowing 5 max and being limited on who pairs with who, it leads to better conversations and more thoughtful combat.
The plot is so stupid oh my god. Path of Radiance still best plot forever.
I like that they kept the Rally skills from Awakening, those were cool
Reclassing is better by still level-capping, but it's honestly a pretty stupid way to develop skill trees. There are so many better ways to allow character custom builds. Just give people choices between levels, have more skills that show up in finite numbers, use point trees like Dragon Quest 8.
Overall I am very pleased with this game. Huge step forward after Awakening, and I am impressed they could simultaneously appeal to the expanded and original audience. After I finish Conquest on hard I will probably work through Birthright and Revelation in Lunatic. Seems reasonable enough.
