2. Is it worth it to use high quality components for every piece of the product or should I be using a mix of high quality and inferior components?
There is
rare occasion where maxing a high quality components and a low quality one would be (slitglty) instresting. To be honest, it's no big deal and one won't really make a mistake to craft the best thing ever with the best mats.
I can think of two situations.
First it concern taser. You don't really care about damage done, what is important is the stun. Damage is based on the electroshock generator along with energy cost of the taser attack. You might want to have a relatively low electroshock generator with a high plasma core to have maximum number of attacks. But again ... You should not run out of power on your taser during a fight if bother core and generator match, so ... Why bother much ?
Second, it concern shield and again it's about better energy consuptions. Never did it myself, but already discuss with someone who planned acordingly. Let's say you have a big fat metal armor with high threshold, you don't really care that your energy shield is passed through if the remaining damage is less than your threshold. A stronger shield that stop 100% of the attack would be less efficient as it won't make a use of your threshold, then in that case, you might want medium quality emitter, smartly chosen, so that average foes will pass your shield just enough for your threshold to take the blow, saving energy in the process. In theory at least. Because once again ... there is a lot of unknown in this and it require advance knowledge of the game to know how much damage you will receive for a really small upgrade. Is it worth it ? Probably not.
Could anyone think of any situations similar to these ones, that at least, in theory, using lesser quality would be better ? With aluminum overcoat or strider to lessen the impact on sthealth, maybe ?
