I have to say that I would not play anything that gave no rewards given the choice. not necessarily xp, merits, ho's etc counted. but if a mob type gave nothing, I did my best to avoid it and ignore it. we heard the "risk vs rewards" BS all the time. yet they had no problem removing the reward and leaving the risk. not much of a rule when you only want to follow it when its convenient.
Then the AE probably wasn't made for players like you, and to be blunt, I surely do wish you had just left it alone.
That's what personally irritated me, this notion that every single part of the game had to appeal to a player, or else the game was broken. I would have
loved it if AE gave no rewards, or if it gave rewards that were only worth something inside of AE. Would the farmers and powerlevelers have played AE then? No. GOOD! AE was never intended to be a farming or powerleveling tool, it was meant for players to create and publish their own stories.
To me, AE was one of the most exciting announcements around the game that I was genuinely stoked about, and it broke my heart to see it so mercilessly exploited. I went from "I'm going to spend practically all of my time in here!" to "I never want to see this cesspool again" in pretty short order.
Personally, I wish that there had been a lot more very visible, very public nerfs to people's accounts. Character rollbacks, locking AE slots, etc. would have been friggin' fantastic, and based on early comments during testing and development that the devs absolutely, positively weren't going to tolerate farming arcs, I really expected it.
Oh well, I guess it's all water under the bridge now, but yeah, I agree with the poster above that basically said that it's not the devs' fault that AE was broken, it was the players.
