First of all as Fritz has a big range he will not properly follow the king sometimes.
On bases like this, for example:
Fritz will stay on blue point just shooting while King fights all the red path! and that causes Fritz to waste his spell on orange path only again and again during all that time!
Gotta decrease the minimum range that the pal can be away from the hero so he can follow us properly, like the melee attack pals do.
And another thing is, when Fritz casts that sliding blizzard spell he will sometimes drag allied units with him, both ahead to just die or all the way back so I have to wait for them to reach me again!
It’s so annoying when I’m trying to keep my army together and suddenly Fritz does that and sends my wolves to Narnia!!!
