"allow SE to hire more ppl"

have you ever coded anything in your life?

more people != quality
more people = more memory leak
more people = more discussion
more people = more time used on not programming.

also, if they wanted money, they wpould make it p2p, but they get LOTS of money from their other games at the same time. People also atually "donate" by buying more ff titles just for this game to grow. They dont need money, they need time.
And if you dont have time for that, well, thats your own problem.

Making a singleplayer part would take about 2 years, are you ready to wait for that? no? didnt think do.
