Imagine Critical is the bra-less lady in the mac ad. Let me free your soul and introduce you to FPA.
FPA stands for (surprise!) Fun Per Action. Critical does not want you to have a second job when you get home and crank open our wonderful world of wow. Base your decisions on the amount of FPA you receive, not for the amount of gold churnable per hour.
This one of the reasons for burnout/wowquit, because alot of you/us/me do things in wow that is not fun to us, but we do it because it increases our GPH which we blindly think a higher value is better to have. If your goal is to have a mil liquid then by all means go hard as Critical always advocates setting a goal and striving towards it.
The better question to be asking yourself instead of Foo's is: Given my limited play time in wow to do anything (including and not limited to, making gold), what is the most fun way I can enjoy my $15.
I say this because I am sure all Critical Readers have liquidity of at least 100k. How much really do you need for repairs, gems, chants etc. Having half a mil liquid was giving Critical nightmares worrying about loss income because he wasnt snatching up raws and crunching them into finished goods. Gifiting it all away meant I could start from scratch and enjoy what I think alot of goblins enjoy doing. Starting with $1 and by playing the AH to see how far you can get.
Really Mox, what are you going to do with 3 mil. Critical challenges you to gift it all away. I bet you will have some very interesting topics if you do.
