You are naive if you think that is the main reason why companies are having a system like this. They have it because it makes more money, there is a reason why bliz does not sell seperate cards or dust in the store... because p2w lootboxes (because that is wat packs are) make more money. 

PS Im not against companies making money, but you can make money of a game while not not including these kinds of mechanics, keeping it  accessable and affordable for players.

People are complaining because they expected a free ticket. It was done like that before, so the expectation is not unreasonable. 

The fact that hey put gambling in a game like this, is on itself disgusting. That blizzard also refuses to make the first entry free, even though most players would get minimal returns out of it, is pure greed.
