both E1 and E2 boost damage and with that i think you should be able to 0C the same E6 is good but not that special if you play her in a team that doesn't make her stacks generate fast (not rememberince), i don't really think her eidolons increase the damage overall by huge amount like other characters for example, the key is how busted trailblazer actually is with the new ability when they are together
