as an autobattler i use notation in my head for enemy formations that reads x+y+a/b/c where
x = troops you hard/soft counter
y = troops that are neutral (same)
a/b/c = troops that counter you hard/medium/soft
anyhoo have discovered that formations of 3+1+a/b at like province ~22 and above that used to be fine can now completely ruin your day (unless maybe you're going super ham on buffs?)
Don't forget to factor the terrain nightmare into the equation though...
Had a couple fights today for example in the tourney where I should have easily countered the enemy, for example;
2x Dark Abbot + Thornrose Mage + Myst Walker + Bandit
...so I sent in 5x Xbows and got auto-wiped while barely killing half the enemy line-up! Decided to throw in 1x Barbie just to scout the battle field to see WTF just happened, and low and behold, the terrain was basically a giant barrier of bushes & tree stumps on top of my deployment zone, while the enemy had free reign to run into the giant cull-de-sack on their side and magic me to death, while my Xbows had to circumvent the entire outer ring the battlefield just to get into range!
Had another fight that was;
1x Thief + 1x Ancient Ork + 1x Hellhound + 2x Archers...
Threw 5x Mortars (god these guys are so useless!) and got auto-wiped yet again... chucked down a Barbie for a peek at the terrain, except there basically wasn't any this time and my Mortars got their faces beaten in by all the enemy light infantry. (...so much for having an "advantage" >.< )
