You saying that 376 more health on Thousand Blosssom set is critical for survival? And even more, 30 natural mana regen?
At Yakhmar you'll always have max mana when They Hunger comes, due to the +15% mana tap on spellweave. Line up properly and do one Lance of Mitra on the mob furthest away and you'll probably be maxed out on mana.
At Honorguard, Igneous, Lotus Domination, you'll wear some const items / T3 accessories anyway.
