Heh, well... in the end imprinting is
still basically the most powerful buff you can get overall, although for some builds/styles/players it is no longer always the clear front-runner, so it seems to be in a really good spot balance-wise.
Note that getting exit intel is not meant to be a reliable part of imprinting, purely a luck thing (it's intentionally set as the rarest Zion intel, by far!), so you'll need to find an alternative way to locate the Access exit anyway.
should imprinting really do more for bots who move faster and have less need of allies?
It's interesting you mention that because imprinting is not necessarily all that often used by these bots, as they're usually capable of hacking and can get more use out of Terminals by comparison.
In practice Zion is a more common ally for combat bots not primarily for the possible intel (which is pretty random and should be considered incidental), but for the occasional ally support and
especially superior parts those allies can leave behind for you.
Losing Z-Hack support on one floor just means leaving that floor sooner if you're not ready for what else could happen, but Access in particular is going to be a challenge due to its size, which is fine since it's the last main floor.
