Well it would be kind of stupid to base very many achievements on the capabilities of the top 5% of their player base. I imagine the average player is incapable of killing cosmic doom in 60 seconds. I imagine most players can't even do Genosha, much less get through encounters with zero deaths. Hell, I still haven't gotten a zero death Onslaught farming him with a group composed of most of the best players in my SG. The game is about grinding just like most of its genre, it's no surprise that most of the achievements would also be about grinding.
Although obviously some of them are pretty fucking stupid, like 100 holo hulk kills for Hulkbuster, or 2k sentinel kills with Cable. Seriously, two thousand sentinels? It took me several hours to farm 2k frost giants on Loki and they appear in low but steady numbers in Norway. 2k sentinels would take a fucking life age of middle earth.
I'm just shy of 7k points, and War Machine should push me over. That final push to 9k is going to be awful. I'm also not looking forward to my options to finish the 10 titles feat. I'm at 6, Demonslayer and Maximum Onslaught will be an easy way to get to 8, but the remaining options are pretty awful. 5 more cosmic prestiges would get me 100 points and a title, but that would drive me insane. I suppose I will inevitably get the armor event title and uniquely qualified, although it might be possible for me to get the mayhem event title before uniques. Only need Magik for mayhem, plus killing thousands of demons in midtown and limbo.
The Shimmy Shimmy Ya achievement is fucking retarded though. I've done around 50 limbo runs, and I have less than 100 kills of everything except mindless ones. So what is that, over 1000 limbo runs for the achievement?
