Spending time and effort achieving something does not make it inherently more valuable. Especially when it comes to MMORPGs; games which, by their very nature, are designed to waste your time and keep you playing (and paying) for as long as possible. I get that seeing the "mission complete" popup, or getting another level, or unlocking another power, are all dopamine hits, but that's all they are. They're not accomplishments. Anyone can do it if they sit at the computer for long enough. Leveling 1-50 the regular way is just as easy as AFK Farming, it just takes longer.
I realised this pretty early on with CoH, so I found my sense of reward elsewhere in the game. By creating interesting characters, telling stories with them, and all the stuff I outlined in my last post. So, genuinely, nothing's been lost for me. I've been treating CoH as a creative sandbox/SuperheroSIMS since 2004. It has been, and continues to be, a lot of fun. If anything, being able to AFK farm 1-50 in a day, and then AFK farm as many vet levels as I need for incarnates, has added to the fun. If it was harder to do this, I wouldn't still be here.
