Upgrade or alternative upgrade?

I wanted to just write it, but since I'm already doing it, I'll express my opinion by commenting on Valhalla's post ;)
Overquoting

1) I meant a wall of fire)).
2) Also, a clear example would be the archers running away from you, which you chased across the entire map in version 2.1, and the harpies in 3.0 (it happened to me many times).
3) Berserkers are more useful, in my opinion, because they occupy only one cell, while you can only protect archers diagonally with bears)).
4) I won't elaborate on Jarls yet, I can't prove that they are better.
5) But the Arcomage Dragons... Play as Helmar on a duel server, and everything will become clear; it's a mini wall of fire, not a weak flame.
