If you examine cards after you acquire them then it doesn't feel like you are ever spending hours going through the entire collection hunting for runes. Although cumulatively you may spend hours, 2 minutes here and there over the months doesn't really consume much energy. Also nobody searches for trials. They pop up and you beat them or you don't, but if you are playing the game just to ball then trials will pop up now and then and every once in awhile you will beat it. Lastly, many dedicated players have 750k without spending hundreds of dollars, the game has been out for months now and if you spend the majority of your time on MyTeam mode you can get pretty far. Casual games are not afforded that luxury.
Steve Nash is not a bum, he is incomplete with missing badges, plays, and hotspots, however, he is still deadly when used right. I am sure if you played Larry at the 4 spot he would be lethal, not slow at all compared to other PF's, and his lateral quickness is 80+, he has the height and post D to bang down low, plus exceptional post fade and passing skills too. Seems like a steal for 750k considering the only other card currently in the game that is rated better than him is 81pt Kobe that goes for 5m+ in AH.
