Let’s think about this from everyone elses view except the thiefs POV, the only way for someone to currently get back their printer if it had security upgrade is 1. Relog, 2. Have it destroyed somehow, 3. Raid and take it back.
Thiefs would ultimately abuse this power and take every printer in the server and people not being able to get them back other then to raid them which in this case if a thief is getting away with something like this than their base has to be something else. It would in the end piss people off, let alone someone actually being succesful in a raid on a base that had everyone else’s printers they would all need to be destroyed because it would just be abuse upon abuse.
No one else would play any other job except thief and there is a large quantity of people that can play thief but it’s not unlimited, so if regular thief spots get taken up people would be forced to buy ranks just to be thief causing absolute chaos. That right there is the true “non-sense”.
