Let me spell it out for you logically so there is no further miscommunication.
premise A) you have some FI engines that have bent rods at various power levels.
premise B) you also have completely stock engines that have bent rods
premise C) you also have high power FI engines that have lasted tens of thousands of miles without incident
Conclusion (You) FI will increase the likelihood of bending rods...
I'm sorry that's an invalid conclusion based on the premises (which in this case are the evidences).
If those premises are true, AND THEY ARE, then the only conclusion that fits the premises is that there is a quality control issue on the rods and some engines are susceptible and some aren't regardless of whether they are BONE STOCK or making 350WHP on E85.
A further conclusion that one could draw (although this one requires inductive reasoning) is that if you are unlucky enough to have bad rods, they may bend even if you don't go FI and there's no point in worrying about it if you WANT FI...
Now if you want to make the conclusion instead:
Conclusion: If you have lower quality controlled rods, FI will be more likely to cause failure.
Then you have a somewhat more valid conclusion, but again, that should have negligible effect on whether you choose to go FI or not because you may bend a rod anyways just N/A...
I personally have seen three engines come into our Toyota dealership that were ALL N/A that bent rod number 3.

Jaden - I said you increase the likelihood. If you're putting more power through a weak point you will increase the likelihood of failure. FI does that. Rods are generally regarded as a weak point on the FA20.
To have a bent rod while NA is not unheard of, even at stock levels. It is not just in this vehicle, and QC issues seem to be on par for other Subaru products..

Does putting forced induction on this vehicle increase the chance of bending rods or having other bottom end issues MORE than leaving the vehicle NA?
Assuming proper tuning and oil level and maintenance.
