I started around two months ago, and regularly spend around 20-30 hours/week playing the game. With that said, I'm taking my time slowly progressing the MSQ.

But now my highest class is at lv70, and a couple of others at lv66-69, I think it's time for me to come to terms with reality and ask the question just how many classes can you main with optimal gears for endgame stuff all that with the amount of free time I have?

How about 1 tank, 3 DPSs and 1 healer. Five times the grinding I'm assuming?
