have you admit that after you play with all credos and donates once = you cant play without it
game looks defective when you have no 10x11 inventory and dont have 20% free Q , speed and output
so all you doing when come back to the game with fresh character you start to grind credos and mostly not play the game until target credo finished
what do you think about :
make credos buyable
make it simple (like game start guide (few quests to understand how to play)) and start to play with credos not after half year of grind quests
make it most part of gameplay ( make quests not tedium\impossible\repeating or\and let us do them 24\7 with no log off for curio or harvest quests )
