I gave him a FULL FREAKING list of quests that would have cost me 2m or so to complete, 7 hours, and tons and tons and tons of headaches. These weren't mundane quests either; the majority were painful, hour-2hour long quests that would have made me rage at the game.
Prior to working with him, I price checked 5 other questing services for the same exact quests, and most of them charged about the same related to the others. Wantacookie basically cut the price by 40%. I'd go as far as to say he's genuinely one of, if not the, fastest, cheapest, and easiest questers providing service today.
I gave him a huge list of quests that would have taken decent questers 7 hours. He finished them in 5. In addition, from the time I placed the order to the time my quests were finished was literally 12 hours.
He's fast. He's easy. He's cheap. And he did all of this... on my pure. Without a single scuff.
10/10 would literally kiss ass on a vouch thread for him, that's how much I endorse this man.
