They put a limit cuz otherwise anyone with 350K gralats could get Max gifts without a single person actually getting them a gift. It's good that there's a limit imo

If they want to reduce lag it'd be better to allow gifts to be opened in the morning , so everyone can open them when they get up , rather than everyone being on at 6pm EST and trying to open them. It's easier just to log on the next day and do it for me
