serious suggestion: summon towards specific champions
ok so it seems that specific champions are more valuable than others. Unfortunately even if you spend 1000000$ you might never get them with the current system . I have seen in other games that there is a summon of all specific factions (apart from the general one) , and every time you summon one by one the champions of the faction are removed from the list until you get the one you desire eventually ... that is a fantastic idea that also makes you spend money but at least with a target and you feel rewarded. Please consider this for us that have lost the chance to get a champion when he first appeared ...Money you spend in life must have a purpose and are not usually gambling (unless you have a mental disease) . And this is a doctor's opinion...
Other than that the game has many features and is quite enjoyable
