I'll make this as quick as possible. If you need an explanation, just ask below.
 * Umr-5 is a terrible LRIG.
 * You lack Servants. Servant Y may help, but you need at least 7.
 * Too much Metsumi. Try 1-2 copies. Or none at all.
 * Ifrid's an unusual choice.
 * You have 10 level 1s and 11 level 2s. You can't open consistently with that lineup. Try putting at least 12 level 1s.
 * It's been said before, but it's important to say it again. Your ARTS need to be more varied and less situational. At least put a Miasma.

That's about it. I think the rest of it's been addressed by User:GrimRevenger below.
