In my experience, coming from a glad with 3km.def uncharmed, a mage utterly destroys me in PVP (In uncharmed fights). A warlock struggles, and needs to use ice to kill me or else I'll heal off their damage, but a wizard annihilates me, with or without ice (thanks to LN Tbolt kiting).In charmed fights they have no chance period, I heal too much with HP stones / housing and get too much of a m.def bonus in comparison to their m.dmg bonus.Warlocks are a troll class here, they're only the superior PVP class in Mage v Mage fights, all other times Tbolt from Wizards completely negates the tiny bit more m.dmg warlocks have (Doesn't help Sun Set is nerfed and Magic blast hasn't been buffed).
I completely agree mages need a buff to an extent. Wizards are pretty OP as they are, but WLs need the buff.
