Regarding 4-5-1v style, in real-life it might be solely a defensive formation, i'm not sure. In this game, it's very effective as an attacking formation. I personally believe 4-5-1v attacking is one of the most dangerous tactics in this entire game, because most managers play it defensive I think, so it creates a scenario where the opponent is expecting their opponent to be using a defensive/neutral counter-attacking strategy and plan accordingly, and are blindsided by the attacking v-style.
I'm not sure the game engine knows the difference between defensive and attack mentalities. I think their are is a spectrum between neutral orders and extreme orders, with normal/mixed being the most neutral and hard attacking short/long pass and hard defending short/long pass being the most extreme. Neutral orders like normal/flanks/mixed/off/high/normal/zonal/off will should stabilize the engine and decrease the odds of a troll result. Whereas going towards the extremes will both increase the odds of winning as a 30%+ underdog and losing as a 30%+ favorite.
Here is my club history, it's just my attempt to establish some credibility. I understand others have a good history in this game and may disagree with me. But hopefully this at least helps result in my ideas being given some thought, even if it results in them being proven false.
