Harmony - Troop Symmetry

The thing is, when you add silencers, the chance of getting offered several useless skills in a row increases. And that means there's a higher chance of ruining the skill progression. If there wasn't any randomness, it would be a different story – situational silencers wouldn't bother anyone. By the way, silencers have already been tried out for all races – in a certain English-language mod called RPE, I recommend checking it out on the heroes community. But in the end, they still tied the silencers to side effects, in the form of summoning elementals to cities. Because pure silencers... that's quite a mess.
