Ah if you mean you watched my stream, that was back when RIF was first introduced, and it's gotten a number of buffs since then (I will be doing another at some point). It
does, however, tend to take up a fair number of slots if you want to take the widest advantage of it. (Though that's really how most play styles work--gotta double down on it if you want that power!) Beta 8 also added the Hcp. storage, so carrying even more couplers is a possibility, not to mention the other advantages added since I did my run, like higher coupler value and free Garrison hacking.
Derelicts are outside the scope of couplers, so that's not going to happen (who knows, maybe one day there will be an alternative, though right now the other methods are required when against derelicts, which isn't
too common anyway, since most are friendly to begin with).
System shield protection is not that high even when meeting P-70, once you see P-80 it is useless unless superstacked.
Right, that's why I said I think it should be buffed given the new rules. Under the
old robot hacking system, people did raise armies through hacking and allies weren't as valuable since they were a dime a dozen, whereas now a Programmer is quite a dangerous enemy. I mean they're supposed to be dangerous to allies and I don't want to make it too easy to counter them, but we could definitely use some buffs there.
