Well, to get back into argumentation, on an income "scale" I definitely agree with you that fiesta differs in the way of when you obtain the gold, since it does not give you a "constant" income as the other masterminds do.
About my point to play regular vs Fiesta like any other Mastermind I think you partially misunderstood me. In your example you equal up the enemies "behaviour" and mine, (eg same leaks of which the enemy ofc profits more than me) which was not meant by that.
What I was talking about is, that if I sense an enemy playing very weak for certain waves I'll try to aim for a certain punch, this independend of if said person is a fiesta player or not. The Fiesta player usually only has a pretty easy game on guessing, if the opposing player is using autosends, since usually upon even small saves, the fiesta player gets into a gamble. The sending player can however confess to go into eco to not fall behind himself, while the fiesta player might hold, not profiting from any additional gold gain. Also worth noting, a fiesta player suffers harder from being starved, since a too big leak on him will cause an extreme Fallback, if he just continues pumping workers, ignoring the danger, often resultint in a leakspree, which ain't good for him.
I get your point of "increased RNG" though, but yet, I don't see the impact on a too heavy scale as you do. I've played both fiesta myself and have had fiesta in the opposing team and for my personal interpretation, I did not sense a too much difference, except for mildly increased aggression potential (aka workers) towards the player getting sended by said fiesta player, while the fiesta in earlier game is mostly also easier to break. A "glasscanon" player, to say. I (personally) see it as another "legit" source of RNG, similar to other masterminds / fighter selection, It's a high risk / reward race similar to Yolo, even though the mechanics behind that differ in a bigger way.
