Nex has ice prisons and the mage attack on Zaros can hit high (though the only time it'll actually do full damage is when people turn off prayer to heal with resonance..)
Nex doesn't really hit that high unless you turn off prayer and use berserk. Prisons are meant to be avoided, in a team fight at least.
Thing is though that ranged prayer at qbd is not an acceptable strategy when magic prayer at nex is a must. That's why I say qbd hits the highest among bosses lol.
