A THREAD FOR NEWCOMERS!

Hello everyone. Please answer:

3) Why is Sir Mullich banned?

It's all about his specialization. The thing is, speed is one of the most important characteristics of troops. A particularly important nuance is RELATIVE speed, that is, who moves faster: your troops or the enemy's. Having a higher speed allows you to perform many tricks with neutral troops, almost without consequences.
The simplest example is a double strike through a wait (our turn: strike with a single unit, it dies from the counterattack, then wait with a single unit, then wait with another single unit, then wait with yet another single unit (these 3 single units mechanically protect the main squad from morale), wait with the main squad, the neutral's turn, strike with the main squad, strike with 3 single units, new round: strike with a single unit, it dies from the counterattack, then strike with two single units and the main squad. If anyone survives, they will be scared of the main squad and will most likely attack the single unit. In total, losses are 2 single units on the left flank (a distraction for other squads), 3-4 single units. In total, let's say 6 units (possibly not your own, from a third hero). Otherwise, they could have taken out a third of the attacking stack.)
Sir Mullich has a kind of weakened mass acceleration that works right away. This gives him a very serious offensive power against neutrals (more precisely, minimizes losses), and if he could be upgraded into a main hero, it would give him a significant advantage in more serious battles.
