I think you're a bit optimistic.
It's probably going to take closer to 8 weeks. with an average of 2.5min per run still playing 24/7 during those 8 weeks.
Also, just a sorc wouldn't be enough to prep cs fast enough. Hammerdin + bo + sos is the setup for clearing cs at a decent enough speed..
The amount of players and coordination your setup would require is too much, unless you own a small company of paying workers to do it for you..
Even at an advanced clearing speed of 2min, according to your needs, it takes 5 teams to match 2.5 diablo kills per min.
5 teams with at least one sorc and one pal. (bo can be loaded) makes 10 people playing your 2 weeks 24/7, which is impossible, they need sleep.
Say they play 8 hours a day. Now you need 30 people that play 8 hours a day, coordinated, for 2 weeks straight.
Then the main character would need at least 3 people as well, to match the 8 hours a day.
So 33 people, working in perfect synch... ain't gonna happen.
especially when you say 3-6 hours per day, per persona, would increase 33 people to 44-88..
Perhaps I am missing something..
Curious to hear your thoughts.
