Less Useful Rigs: Some rigs, unfortunately, fall under the category of fairly useless, possibly a waste of a rig slot and your Dofus Kamas. One example is the Warp Core Optimizer, which decreases the amount of capacitor required to warp a given distance.
While this sounds like something that might help new pilots with low skills, it requires just as many components to build as many other rigs, rendering it as expensive as more useful rigs like the Capacitor Control Circuit.
The Emissions Scope Sharpener and Memetic Algorithm Bank rigs increase the chance to be able to open archaeology and hacking containers respectively with their given module, Analyzer for archaeology and Code-breaker for hacking.
Given that the only places to find these cans are in COSMOS complexes or explored profession sites (see p58), both of which require a decent combat ship, most players will simply fit either an Analyser or Code-breaker to their combat ship.
Since access difficulty simply determines the chance of the can opening on each of an unlimited number of attempts, these two rigs are completely replaceable by a little patience - something that doesn't cost 200 calibrations and a rig slot.
Also, contrary to the more popular superstitions out there, using these rigs will not improve the loot found in the cans.
