Practically? I DID solo all the way to 80 in AoC. Content was great up to that point, don't get me wrong.
Certain points that killed it for me:
•AoC required SO FUCKING MUCH from a computer in order to function and experience all the great graphical components. I had a typical computer, by typical I mean that it ran WAR with most graphical options maxed just fine, and in order to play AoC with more than 5 FPS, I had to turn everything off. OFF. As in, any potential cool visual effects... I didn't see them. I saw my guy swing a big ugly sword at some semi-pixelated douchefucks.
•End game content. Wait, what? People were supposed to make it to 80 and expect something to do? Yeah, no. Once I finally got up there, I dumped some trash guild I was in for some reason and joined the #1 on server. There was one instance that was runnable. One. I went in once, it was full of tight ass corridors and glitchy pulls. Also, back to my FPS here; Even with all of the settings down, I was having a field day with some wicked 5-10 FPS.
This is a shortened version of the bottled-up rage I had almost 2 years ago that I never really let out. It has greatly diminished since then, as I feel that my anger has been relinquished by the uber suckage that is AoC get flushed down the toilet by society. Also: EA is dumping all kinds of development studios and cutting back. What does this mean? Bye, Bye, Mythic!
