I may not compare getting relics with something that come from summoning souls. Relics are gotten through effort and time spent either on PVP or gauntlet.

Not have good experience summonig souls like many people here, when eternals first were released it took me like 20 souls to get Clair, and there were only 4 options with that soul. Now there are 9 differente kind of evo materials and we need 5 of each to upgrade the specific talisman we may have.
