Shiroe face at that last moment.... Someone gonna get trolled hard next episode
Well shiroe did bring the under level because as it said before, he bring the one who resist the sleeping debuff, which so far works allright.
Being (seriously) under level in high level raid is not that scary actually, especially if your group raid is compose of your best bro/friends, even if they going against level 90 mobs as long as their tank keep aggroing and position himself ahead of the mobs (mobs back facing the dps), its 90% safe with aoe attack is your only concern, and under level shouldnt be able to compete with aggro so its pretty much free hits.
