…either you’ve played Eve long enough to have the knowledge to very easily answer that yourself, or you have not. If you have not, you really shouldn’t be posting suggestions for changes.
You asked for numbers, but honestly, it’s the concept that matters. I could quote dozens of fits, but without explaining the logic, the underlying message could be lost:
Ships have limited PG. Even battleships. This PG is added specifically to force them to make fitting decisions.
The moment you add a new module with 450 PG (to put this into perspective, a T2 LSE requires 160 PG, which is what battleships fit now) you’re very nearly tripling their PG requirements for buffer.
Without a corresponding increase in PG, most fits won’t be able to fit these without expensive sacrifices. Expensive sacrifices get overlooked by people who min/max.
