Where I think people justifiably start to want a shortcut is where they are being forced to carry out a completely mindless repetitive task quite literally hundreds if not thousands of times over ... such as flying at slow speed trying to force High Grade Emissions USS to spawn, or sitting stationary next to some NPC ships that are jumping out, scanning their wakes over and over and over again until the game rewards with a very rare 'lootbox' of data.
3.0 has made huge inroads into removing 'the grind' but if you look closely, what people tend still to be complaining about most are these repetitive, unfulfilling loops of non-gameplay that are quite difficult to avoid if you are unlucky enough to be pursuing a chosen upgrade path that demands several of these materials (for literally no reason - lots of other arguably more powerful upgrades, don't).
While I am very much a 3.0 fan, I recognise these choke-points still sometimes exist and cause understandable frustration.
...and therein lies the problem. You, as a "dumb pew-pew" may not see that, but what you call "loops of non-gameplay" (namely, doing missions, driving an SRV, flying through space and visiting various parts of the system,...) makes 100% of gameplay for some people (well, me).
How much do we disagree, though? I didn't identify non-combat in general, I identified two activities in particular (HGE USS and Wake Scanning) which in turn are associated with a few of the remaining choke-point ToR ('Top of Row') mats. Each to their own, but do many really enjoy these two activities?
Or they could just add some kind of trader who would trade materials you get by doing combat for those you currently need.
Unfortunately this is @Hellakitty's and @RedAnders and others' point.
Because the only way to trade for a ToR mat is (at best) 6-1 it's actually quite difficult to achieve the few choke-point mats via trading.
If someone wants to max out 5 x g5 modules requiring these mats, they need to put aside 50 of these mats to do it.
That means they'd need (at best) to trade 300 other very rare g5 mats for them - quite an undertaking.
The point here is that these mats are anomalous. I actually didn't have any problems making my first fully hard-ceiling PvP ship, but that's because luckily for me, it needed hardly any of these mats for my particular spec.
I pity those in a less fortunate position ... and hope that Frontier clear up these anomalies soon.
To be clear:
(A) Imho 3.0 is really good
(B) Most ToR g5 mats are pleasantly easy to acquire
(C) However some remain very rare
(D) And some of those require a mindless repetitive task to be completed - no way to avoid it - until the lootbox appears
(E) The Mats Trader is great for many things but not for items meeting criteria (D)+(E) above due to the 6-1 rate applying (at best) to very rare for very rare ToR trades
