S'pose it's how the player decides to kill with the Wiz then. o.O Seems easy for me.
o.o sorry but rly? xD sorry darl also gonna disagree with ya here. As a wizard you go for the easy pickin' zerk n' pallies and sages, sin and rangers you can deadzone.
hitting a cleric is trying to hit a brick wall, high M defense, anti-stun and the ability to silence. With the blue build proposed under 'Cleric/Sage section' clerics also become a nasty way to kill yourself (seen this from experience... unfortunately.)
As to original post, +15 pally CAN be killed by the equivalent wizard or necro.
As for clerics, their experimental blue build .... means they gain a bit of potential. with that said vast majority don't roll that so it's fine.
