The most useful monster.

We are not talking about the absolute best, but about the most useful units, and each player is free to justify why a particular unit is useful from their point of view. Therefore, the poll itself is very revealing, as it highlights the following:
1. How usefulness is expressed for a particular player.
2. Which units are leading in this regard.
3. There is an almost continuous discussion about one of the main units in the game - the army.
