Except, like I told you many times already: it's not as important as you paint it to be. I can do combat perfectly well in a non-engineered ship, too. The only limitation is that I should not attack wings of several ships in a non-engineered ship. And I am not a great pilot, either, so I can't credit this to superior skills or anything like that.
If you want your ship engineered, right now, to the max, it indeed is a terrible and annoying grind. If you on the other hand just collect materials as you go and once a while exchange them at a material trader, you end up with more than enough material to engineer a ship. It's true, because it's exactly what I did with the last ships I engineered: I just used the materials I already had stored away. No extra effort, except having to travel around for an hour or two, to visit those engineers of which I needed several items engineered, as you can't pin more than one blueprint per engineer.
It very much depends on how you operate. In case you want to see it as work and want to do it quickly: indeed, it will be highly annoying. But as you don't really need to engineer your ship, unless you immediately want to do things like soloing wing assassination missions, it can also happen quite naturally with limited extra effort. It very much depends on how you choose to play.
The Engineers are not as bad as they formerly were. Would FD finally find the guts to also rebalance the blueprints and cut down the crazy power scaling, they could actually be a nice addition to the game. What I still dislike is to how crazily you can stack up defenses. But luckily NPCs don't really use that system too much, so it's not that big of a PvE problem as some people paint it to be. As long as you pick your targets reasonably well (means: not attacking a wing of two Anacondas and one FGS, all three with a SLF hangar on board), you can still do fine without any engineering.
Same here. V1 Engineers were terribly bad. Their design was based on pure manager greed, lack of understanding of game design, plenty of drugs and perhaps a lobotomy here and there. That's why I also did very little engineering at that time. It was hell of annoying to collect materials for a G5 upgrade, to then just have several rolls all turn out bad. I tried that once, saw what it does to the player and gave up on it. My ships mostly had G1 or G2 upgrades, of which I was able to afford plenty of rolls without having to invest much time into it.
I very much do understand that the old system burnt out people and they hated it. I also did, that's why I ignored it. But the game moved on. Luckily the rolling system was redeemed. Engineers in my eyes still are not awesome, it's unlikely that I'll ever start to praise them. But they are functional now and can be used with acceptable effort.
