I can imagine losing to a roll to a SIM is incredibly frustrating, as you said, they don't even enjoy the game or spend money. That could be a future piece of your team.
This is a weird subject too, because devil's advocate, I don't want to play in a game where the SIMs are even more pathetically bad at the game then they already are. At season's end, they receive all of the players nobody else wanted.
I know you didn't come here asking for advice but just maybe this will help as I haven't rolled against a sim maybe since I started back in 2019.
1. SIMs can't offer promises, rarely offer a respectable amount of AP, and limited HV/CV (if any). You *should* be able to stomp them out pretty easily outside of maybe D3 where money is tight.
2. When a SIM reached very low, it will stop pursuing 99% of the time (I'd say 100% but I'm pretty sure someone mentioned it's happened once so I'll go 99%). So jump on your SIM battles early and just knock them to VL, then you can re-allocate those resources to human battles.
3. When you are the 81% favorite at the time the recruit decides to sign, he will automatically sign with you.
Using those 3 points, if you had early thrown down some promises and knocked down the SIMs to VL, then you could've re-allocated to the two human battles and had better chances of winning.
Is it crap luck you lost all 4? For sure. My story doesn't interest you but I once lost 24/27 rolls with 22 as the favorite (and most of the time, overwhelming favorite). So I get it more than many.
