CrazyEye told you this as well, but it's worth trying to restate for you: bidding isn't restricted to when the auction ends. I've won plenty of bids while I was asleep, working, or otherwise away from the computer. You just need to be willing to make a bid at a price you can accept before someone else pushes it to that level, and willing to accept that you might get outbid while you're out.
And there are upsides to North American prime time as well... lots of free agent or retired players come up at times that are not friendly to the average European but are to us. The servers rarely if ever bog down (causing failed bids sometimes, etc.) in our prime time... when they do, it's during Europe game times.
I guess the last thing would be that things aren't going to change in this respect. So you might as well focus your energy on something else.
