That's what I think is important for offering random boxes. It's not as exploitative if you're still getting your money's worth on each pull. It's when the common result in the box is less then the cost of entry that it starts to get sleezy.Honestly, Rohan's entire post is an interesting analysis, but RJ distills my own opinion fairly well. If the minimum value of such boxes or packs is actually worth the cost of the key, then I don't have a problem with them. Of course, YMMV. However, when the minimum is nil or virtually nil, I feel it has no place "my" game.

Seriously, Blizzard created the Sparkle Pony for (I'm guessing) less than $1,000US, based on models they already had in the game. They made something like $75 million from THE FIRST DAY! Even though I didn't personally think it was worth it, I don't have a problem with that, since everyone who plunked down their 25 bucks knew what they were getting for their money. It's not that hard, Devs.
Whew! Sorry, that almost turned into another rant . . .
