Just out of interest... did you discover the Guardian sites on your own and figure out the pylon minigame entirely by yourself with no external help or someone showing you how to do it? Because if you figured out the entire thing completely solo, you're an absolute genius.
This question is interesting. I didn't get the option to figure it out myself because someone told me what to do! But I've often wondered how far I'd have got on my own. I've since tried to reverse-engineer what my thinking might have been.
1. I'd never have found a Guardian site unaided. Finding those is definitely a whole-community thing.
2. I'm sure I would quickly have got the idea that there were spots where Sentinels spawned, and I'd have learned how to defeat them. Also, I'd have found and taken the materials available from destructible panels etc. easily.
3. I think I would have driven up to the obvious central structure. This would have demonstrated the appearance of the pylons. Shooting into them would have been an obvious thing to try and this would have shown me the countdown. It would also show how many more pylons were to be found. Charging all of them and having the countdown continue would definitely have sent me back to the central structure. The first time I'd probably have just waited there for the countdown to end, resulting in failure.
4. It would then have been obvious that there was a final puzzle to solve, but I don't think I'd have twigged dropping a Relic. With hindsight the small triangular socket is a good visual clue, but I'm not usually that observant.
I guess that FD designed the whole puzzle to be solved with these clues and I think it's a pretty good design. Finding the site is really the hard bit, but that's always going to be a community thing unless many millions of them exist, which would look silly. I think it's fair enough for the final piece of the puzzle to be tricky too.
What the game itself doesn't immediately tell you is what to do with the blueprint once you've got it.
