Not sure if Demongod is saying that you can ONLY gift cards that you have 4+ copies of, or what "some other way to exchange your cards" means. Some way besides a trading system...? In the former case, probably true that few people will really take the time to make alts which accumulate enough dupes to feed their main account, but I also don't see how that helps free/normal-spending players unless you plan to beg big spenders for their scraps.
If you can just gift cards in general (no restriction to 4+ copies), then yeah that's exactly as vulnerable to multiple-account exploiting as a trading system. Maybe it does make Alteil feel more safe about the legal issues, but I agree that those sound a lot like fig-leaf when compared to the multi-account exploiting. It's not even clear how to draw the line about exploiting, by the way. Say InigoNoPay wins a 5* in the lottery that will complete a playset for InigoMontoya; seems like you should allow that 'gift' but not allow icewolf35-45 to gift daily lottery pulls to icewolf33.
I think that http://www.alteil.com/forum/index.php?f=50&t=3985&rb_v=viewtopic (bronze box) is probably a proposal they are more likely to accept.
