Could all symbols be balance so that Primary Effect = G6 and Secondary effect = G4 at G4?
Right now some symbols have G4 effect while others have G7.5 at G4. For example:
Conquerer: G7.5 Ac + G4 accurate = G11.5 of usefulness
Desperado: G4 Force + G4 accurate = G8 of usefulness
Obviously most people would go with the symbol that has the most total grades of usefulness.
