For me you are still a new player. I don't think you have 6 grids finished in 3 months + 6 relic weapons already.
I play 7 months already and I have for each element a relic weapon and I am working for the 2nd one for each element.
I don't really care if I have to use a 100% Eido or 60%. At the evening I will just do GO and it takes me 10-12min with ele adv and 15-18mins without.
Not really time consuming because I have to do GO only 1-3times in a week. And for the other days I will just give up or test my other teams.
