PS/init compression has definitely contributed to higher bidding. Fewer initiative values means that ships are more likely to overlap, and thus bids are more relevant.
There are two worse offenders than PS/init, compression, though.
- Points compression: most ships have a smaller gap between generic and top ace than before. This reduces the effect of upgrading to i5/i6, making i5/i6 pilots more common.
- Pilot abilities: just like 1.0, many of the best pilot abilities are on i5/i6 pilots.
That said, I'm not really sure what is motivating OP here besides "Silly design is silly"
