MAIN REASON why people are not happy about the simulation engine is that they just simply do not understand how does it work - and most probably no body understands, apart Nordeus employees. In order to shut up people, Nordeus must provide some guidance what works against what? Something like this:
  • Attacking beats defending
  • Defending beats normal
  • Normal beats attacking
  • Playing wings does not work if oponent have strong DL/DR
  • Short pases creates 30% less chances, but adds 10% possesion and 10% better conversion rate
  • 20% stronger team have 70% chance of winning if all other stuff is equal

Obviously I just made it up - but guidance like this would be so much helpfull if we knew some stuff for sure.
For people angry at results - I can simply say that simulation is a randomization process in which you never get 100% result. If your team is MUCH stronger, then it might be that you have overall chance of 99% that you will win, but it is never going to be 100%. And remember, everyday there are millions of matches simulated, so troll results are inevitable.
