It feels a bit strange, like why night vision is furthest in the unlock chain, why not the jump assist, or shield regen for example, those seem to do kind of more for you? But in the end, all the mods are just about QoL. I may be too influenced by the fact that i've done most of my CZs in a G3 Dom with no mods (with a torch), but after mods done, i rly kind of underuse night vision... It's still nice to have and i don't think i change it for smth else, but by no mean necessary or required.
Shield Regen on an Art would give you a good possibility to try it in combat, i heard about flying Art build armed with rockets. I never tried in in a CZ, but i was fighting Guardian Sentinels in my Art (usual one tho - my choice was night vision, jump, battery and sprint).
For usual exploration focused Art - in my opinion - jump and sprint are the only really useful mods, after all that's what you do when you scan plants. Then, battery is a good thing, but that starts being optional. Plant scan takes about 12% of normal battery and like 6% of improved one, Art is equipped with 3 reserve batteries - you really need a long walking session to spend all this. I remember myself speding quite a while in some very rough montains that i couldn't stand in SRV and i walked a lot, scanned maybe 5 plants overall there using 2 out of 3 batteries. Was long. Idk if i'm up for even longer walks... So good, but niche. I think night vision beats it (especially as if you walk, the reason is that you're in the mountains = shadows, valleys, and with night vision far plants sometimes are better visible).
Reduced consumption is kind of the same as battery for Art, but i think it'd be worse as you spend some battery on jumps and LS too. Given that, improved battery is an overkill for me, reduced consumption is viable in its place if it's easier to obtain. Then air reserves - it's only for one time, when you're out of power, it ruins that for me. I mean you got 3 reserve batteries, you can make them bigger, you can make your tools use less, and you absolutely got to have jump assist and sprint. All slots taken. Making a super safe Art with battery, consumption, jump and air then? Idk, then you run slower... I also heard combat movement is making you run faster with a scanner in your hand, but i could never see that i'm moving slower with a scanner tbh. Might be wrong.
