I think its probably intentional. Other “system management” skills cost a lot - hauler system management is just over 2 million for example and later skills cost 450k.
Just a side note, but whilst we recently ‘fiddled’ with the Skills recently (mining and lasers / scanners) we didn’t complete our changes. So you can expect to see Pricing on skills moved around a little.
Lots going on under the hood atm (on Dev Build) this last few months so once we have those changes out to you guys & ladies I suspect we will return our attention to things like these pricing values.
