"to protect and to serve"

I've got three chars on my account. Let's say I have 10 with one char, and another 10 in total with 5 in the other two. Count'em all and it is 20 hours. Is this sufficient for 20 hrs requirement?

It makes it mandatory for me to select a main assignment while editing my profile thereby I had to choose something and now I cannot get rid of it. Is there a solution for it?
