My point is there are many reasons one would choose to use this particular overlay. You knew all this though, you're not stupid.
So, I was trying to find a way to respond to this post so that there's as little room for misinterpretation or unintentional offense as possible, given your reaction to my original post. The more I poked at it, the more I realized that it just doesn't matter. The UI overlay is only good for farming resources, grinding world bosses and cheesing through boss fights. I despise farming, grinding and cheesing and I don't often associate with anyone who does. The only possible impact it could have on me is the economy, and the folks who would want an overlay like this are already engaging in that behavior; this just makes it easier. I'm not sure the average player will bother with it either, but we'll see. The in-game economy can probably roll with it, and it's not like I play the "Trading post game" anyways. We'll deal with the slippery slope when we get there (or, more likely, ArenaNet will... or won't).
I do want to leave one little snippet of my post though, if only because I took the time to type it up and am just naive enough to think it needs to be said;
Some of my best memories in Guild Wars 2 (hell, in gaming overall) were experiencing content completely blind. Figuring out the Langmar Estate as a guild, before guides were even out. Doing the Dredge fractal the night they launched and piecing together the last boss' mechanic. That's the gaming equivalent of crack for me, and it's completely counteracted by someone reading the solution, using a guide, etc.
I would rather fail at something a dozen times so I can fully enjoy moment when I do eventually accomplish it. Using a guide ruins that experience for me, whether it's something cerebral like solving a guild puzzle or something more twitchy like beating Liadri.
Liadri is actually a good example, because I was only able to beat her because a bunch of other GAFers were watching, giving advice and helping me learn the fight. I can't make the claim that it was an entirely unassisted effort because I
had a form of help. While I could have looked all of that up and just
done it, that would have robbed me of the experience of hanging out with friends, cheering them on through their attempts, having them cheer me on through mine, having a good time and celebrating when it was finally done. Failing at it all night and having fun together was a lot more fun and a lot more memorable than a title I'll never use and a mini that will sit in my vault forever. If I had just used a guide, it would have just been something to check off a list and move on.
