Ammo stacks don't weigh anything, do they?
My problem isn't the weight (except at vu 9.0 when I got hundreds of animal hides from thorifoids), but rather the number of item points in carried inventory. Let's say 4-5 armor sets, a bunch of more weapons, unused enhancers, (L) mindforce chips I can't decide if to sell, carry or put in storage.
If you hunt on a place like Next Island you pretty soon get 20 different sorts of crystals. And pretty often you get ammo, and when the looted stack is to small to fit into gun it just gets hanging around. So let's say 5 stacks of (same) ammo isn't rare. At that point the ammo needs to be joined. And when number of loots gets too high, you do something just to keep on moving like put stuff in a vehicle. To avoid getting risk of getting stuff lootd, I usaully put things like extra weaons there though so I don't forget anything lootable.
(Other planets have their sorts of stackables. On Calypso it was first the oils, then the extractors, then the tier components.)
If you have <200 items, you run normally, no slowdown.
If you have >200 items, you immediately walk *slow*.
But that is beside the point. When entering space you are entering a different game. Space is a game featuring lootable PVP, and so one should always enter it well prepared.
Well first the obvious: You have never gotten a summon in the middle of a hunt? Or you're always carrying around a Portable Storage Terminal to be prepared?
Secondly: We all do mistakes. Forget to check every box, every vehicle. I'm carrying around a variable amount of vehicles; but let's say at least quad (to travel fast), vtol (if it's easier to spawn), boat (well coolness, and it's got a nice storage), and some sort of car (to spawn fast on ground).
And I got 5-6 "boxes" for carried items and things like bank deeds.
As space "features" lootable pvp, and it's very easy to get there, it wouldn't be bad if there was some easily accessible function that could warn you about the carried items you're about to lose. And maybe even a button that would move all your lootable stackables into storage on planet (including stackables you don't immediately see, like stackables in boxes).
As for lootable pvp, it has historically been for professionals: When you grab the antitoxic shot from trade terminal, you know what you're getting into. And if you don't grab the antitoxic shot, you're safe. Except for space. If you fly to space with someone else you get a warning but no chance to bail out.
Once upon a time there were even signs put up at some places on the borders of pvp areas (even non lootable) (well actually no signs put up around rig are).
