You need one strong healer to allow Lugh to actually do this 700k damage every turn. You have options of Tishtrya (full heal every 6T, 50% TA boost, solid crit buff, 15% ATK/DEF debuff + affliction rst debuff, +10 BG to self on ability use), Atum (solid heal and barrier every 4T/burst with right setup, 50% Vigor buff, auto-res, increased ability power, affliction rate up, cooldown reduction) or Sol (if you need some utility of dispel/cleanse)
And you have one space left and 15%/30% def debuff (Tishtrya or Sol/Atum) to fill if you need it. Even if you don't, there's a question whether risk of losing all self-buffs when getting hit is worth it or not. Generally if you don't use Atum it's not, if you do... it's still probably not, because Atum has hands full with healing Lugh (using auto-res on Lugh and heal/barrier on Vishnu is an option, obviously can't say how it works in practice).
In overall I think, that when Kamihime like Michiru are called shit/bad, there's really something wrong/OP in element in question.
