If, on the other hand, you bought the pick for convenience (which is the ONLY reason why buying it made sense), then I don't understand the bitching about the few silver you are not making. You bought it well aware that you'll be losing money.
Maybe I am WAY off here, but I simply don't like two things about this whole mining pick disaster:
1) Other people getting something better than I, for the same price. (Petty as it may be)
2) ANet changing something that didn't need changing on a whim, just to create more income for themselves. Making something people paid money for, obsolete, in favour of a new shiny.
Could very well be I am just unreasonable and it's really not as much of a dick move as I currently feel it is, but right now - I am still very much bothered by that implementation.
PS.: I don't care for the pick not paying itself any time soon, I didn't buy it so it would. WHICH DOESNT MEAN at the same time, that I don't care that the sprocket pick will amortises itself quicker than mine. Hell yeah I care, bugs the shit out of me, ironically enough!
