Hi Jimeous, welcome to the thread.
"Guides" (I'm not sure Alt-1 falls into this category, but I'll say it does to avoid semantics) can be both helpful and harmful for video games, depending on
how
they are used.
ALT-1's website has a Clue Solver where you just need to paste Screenshots to, so you don't need to install ALT-1 for it.
Which means you will also propose banning using sites like was done in the past for anyone that used Quest Guides, heck AFK-ing was once bannable.
They're not the same so I wouldn't propose that. Using their website is 'the lesser of two evils' but I personally wouldn't use / support them. What's wrong with using Youtube or the Wiki? Again, this comes down to manual vs assisted vs automatic solving. Alt-1 is auto.
ALT-1 doesn't play Runescape for you...
So whether you install ALT-1, use ALT-1's Website or use other Websites for solving clues, all of those methods require a person to actively interact with RS3.
'Playing the game' is more than you just physically clicking. We're tasked with processing information. Alt-1 takes that away and replaces it with whack-a-mole clickable on-screen indicators. If it can be used for clues, it can (and will) be used for other things. No bueno!
If any of those methods had a major affect on Clue Drops then the prices would be way cheaper BUT, Clue Drops are random and most people don't like doing them so prices are stable and the rares tend to be very high.
There are way too many things at play to be certain of that. This is speculation but I'd assume prices would change a fair bit if fewer caskets were being found thanks to Alt-1. That said, it's not really a concern I have, everything is relative. The issue I had, regarding 'that' was you can make way more money letting a script (alt1) do the heavy lifting, more than any guide could.
And by 'guide' I mean anything that teaches you.
