I'll try help you as much as i can know through friends chosing each class.
To begin with you won't realise this when u cap at 105 but Wizard = PVE Warlock = PVP
Im sure you know what both these mean, as you reach 110 120 129 Warlocks will not unlock any new AoE Skills wereas Wizards do.
Summon: Summon's 3 Skeletons to aid you in battle *Not mobs you kill like josh said*
Ummmm skills: ....
Blink(Wizard) and Mezmerize(Warlock) have been missed i couldn't see skill info so sorry
I'll hunt for some 129 Cap skills if i can, need to ask some friends on the korean version so might take some time, but hope this helped ^^
