Just finished, final thoughts for now most likely. I intended to replay this as among other variables such as shop special items and the loot found for that fog of war level I began the final level with only 18 units left alive. Which is to say, several were lost on the way.
As with the second to last map I found the constant reinforcements not fun (albeit was much more fair on the previous map) and found Terror to just be plain unfair. Maybe I missed something but there seemed to be no counterplay. As mentioned before in my list, Freeze seems much stronger than every other status effect. Frost spriggats are very scary as such.
In the end I gave up trying to block tunnels, go for the chests or levers. Instead, lured boss to fly into the lava field and then with a flying Whisper Mega Stabbed (backstabbed) for a OHKO.
Kind of wish there was a sandbox-y postgame but looks like the remaster will have much more freedom in that regard.
I couldn't figure out how to recruit the second Assassin or the Stone golem.
To finish, only other things that come to mind are disappointment from:
1) Being unable to buy more wrenches for my poor Machinist
2) No recruitable spirit (unless I missed it?).
3) Cavalier felt like one of the weakest units offensively, this may in part be due to bad luck on str rolls however. Charge isn't reliable enough to use as a stun either. Although worth noting it's one of the few classes (I had left alive) that hadn't promoted so maybe things changed.
4) A few units (cavalier, and what I call "mages") suggest they can learn counter, but presumably it has a very low weight in level ups. Sadly I wasn't able to get any on those classes of my own but despite meeting some foes with them.
Overall very fun, but I wouldn't advise friends to buy unless on sale.
That's mainly due to the lag in longer fights and lack of user made content that a new player can download on a whim. This series needs more advertising!
Was wondering, does frost resistance lower the chance to be frozen as well and not just damage? And if so I'd image it's percentage based and not subtracted. Would be neat if 50% frost resistance made units immune to freeze though. Could have just been bad RNG, but every "Control" attempt I made on enemy Shadowlings failed (they have 20% mental resistance) which made me wonder about this.
Here's to hoping the remaster is near completion but I won't hold my breath!

Now to see if I can copy main campaign and just tweak a few things for my liking such as teaching psy healers a skill to "clean" status...
