You know, the extra 20% Elemental attack is way worse than having access to Hraes' debuff... going from -40% Def to -50% is a 16% damage increase, whileas that extra 20% Elemental (which even requires you to use multitudes of Wind Eidolons and will thus lower your base attack) is... 8% at the very best? This is with no elemental advantage, no offensive Relic weapon, no elemental buffs and a 40% Eidolon on you.
