As an example I bought deal of the month gems which gave a total of 4000 to play with on the VIP portal.
Of the 4 heros I had Shade maxed and still needed tokens for the other 3 being Lilly, Kreel, and Ferno. After 10 summons I had 8 with a Shade and 2 with Lilly.
Statistics would mean I should have had 2 or 3 of Shade not 8!
In light that players are buying pixels and have nothing physical in return for our money Im sure we would all appreciate a fair and more varied selection with this particular portal. In the Great portal and Heroic portal a player gets a fixed reward for 10x but not so in VIP.
Alternatively allow players to select the 4 heroes beforehand or at least not give the same hero as the previous result over and over.
When it comes to gambling machines in casinos its law to state the % of success but not the case with such mobile app games.
It's evident from example that having 4 heroes in VIP does no mean there is a 25% chance of getting each and I've no idea what the % is to get full unlock. Such variations need to be made aware to players along with the % chance of success when upgrading a rune.
