Actually there may be a problem here. If I remember CoD4 multi player data is stored on your system not server-side... so I'm sure he can keep his name / friends list and such but he's going to have start over from zilch again for CoD4.
I've had it freeze up once but it's pretty rare, as for best moment I'd have to give it to landings mines on warhawks that hover too low to try for easy kills.
From the few games I've played and downloaded.. you can easily eat up 20G. It may be because I often use multiple saves in a single game but you can count on using up towards 5GB on one game from what I've seen. Also some Demos and other things can range anywhere from 500MB - 2GB from what I've...
I don't know if it'd be worthwhile to wait til mid CS, usually I had an idea whether or not I had failed so I would DC right in the middle of it and keep trying.
And it's also possible for PLD/NIN to outperform PLD/WAR on certian fights provided they have the right setups in equipment as well. The closest way to explain is to just look at NIN/DRK with haste for Stun, PLD/NIN can haste setup for Flash and results are close.
Pretty sure it's here to stay as well SE made comments about giving DRK's a reason to use spells, so considering how the rest of the update was ( baring server / login issues ) it seems to fall into place.
If you haven't although I'm sure you have reset the modem and test connectivity from your PC outgoing and see if you're dropping connection at random or such.
