Is diplomacy necessary?

Actually, all these statements like "I recruited 500 minotaurs!", "I recruited 200 titans!", "I recruited 100,000,000 azure dragons!" don't seem very convincing. I don't know what constants are used in random maps, where half a thousand monsters grow in 4 months, which are eager to join, but in campaigns and scenarios, diplomacy is a completely useless skill.

I'll say this:
sometimes, in 3-4 game months, 500 monks join. They just don't necessarily have to be in one group...
183 red dragons joined me. That's my personal record:)
And in general, diplomacy is not the most useless skill. You can recruit creatures, and you can almost bribe your way out for free if you're caught far from home...
Of course, it's needed, but you need to know the measure:)
In an online tournament, it's really not useful - it's unfair... I would say it's unsportsmanlike:):)
