You just said using CM was boring and then 2 sentences later said you were going to grind LL 40 and 1M credits because... wait for it... GRINDING IS FUN!
Really? When did grinding become fun? Mind numbing, sure, and I guess if your mind needs numbing that could be beneficial. But FUN? More fun than sticking hot needles in one's eyes, but significantly less fun than anything else you can do in the game.
How about looking at it differently? This offers people a choice. Those who aren't LL 40 or don't have 1M credits can use CC's. Those who have LL 40 and 1M credits don't need to use CC's. Different approaches for different play styles. Win-win.
This is the problem most people have understanding about this whole ordeal.
