Since the opinions vary, there could be a option to turn RNG off. By default it could be turned on but I think most people would turn it off if it was possible. Then of course we would have two separate group of players, but I don't see a problem it it. It should be about making everyone happy. I think the overwhelming majority would turn RNG off if there was a option.
That is why we have more than 1 rts game on the market This game is about risk management and as such must have rng in. Other games are about quick micro and they can be played exclusively by people who hate randomness.
I played quite a lot card games as well. When you play cards, you know it sometimes can be a pure game of luck where skill means nothing. Nothing can be done about that. However, for RTS games something can be done.
Depends on the game. But in professional poker competitions there is no place for "pure game of luck where skill means nothing". The winner is the best player.
