For the price of the packs, you should offer more in them. They are very slim in what you get.
there are good 5 USD and 20 USD packs. However, IGG needs to adjust hero packs. 5USD pack gives 15 soulstones and 20USD pack gives 18.. they could just scale the soulstones for 20USD packs.
I don't think they should change the pack content.
I would like to see the addition of more low cost packs.
If I had 20 dollars to spend, I would rather buy twenty
$1 packs instead of one $20 pack.
This would also solve OPs issue of pack content. You might get lower quality items from low cost 0acks but you would get alot of it.
