I mastered wizard and destroyed in pve. I'm not sure what your problem with it is.
You .. "destroyed" in pve ? What ? What am i supposed to understand from that ?
Okay, maybe you need some basic math.
Assuming you won't risk going melee much (woo, diamond hoe for .. 25 damage or something), a level 30 wizard does
- ~63 dps (actually 10% or so less but let's dream)
- he has to use fireball, icebolt and bolt with a 100% uptime (which is technically not possible but heh, let's DREAAAM)
- for a cost of 39 mana per second
Average mob hp i've seen so far have about ~1200 on average (basic mob, i'm not talking about pig zombie with 1700-1800+)
So on best case scenario about your dps, it will take you ~20 seconds to kill a mob and you'll burn away ~800 mana.
This is a best case dps scenario and i'm exagerating a lot on how much dps you can do. I think, at best, you'll peak at 60.
Take ANY melee class. Give it a non enchanted diamond weapon (it costs lose change really)
Look at their melee damage, take into consideration that they can have enchantments, take into consideration they have stats increasing their damage, increased damage versus pve and i'ts even probable that they can do even more with the 1.9 swing time adjustment.
All melee classes (okay maybe not the paladin, not quite sure) does more dps than you with a left click.
There's no caster who "destroy" in pve unless he's already full T2 mastered (basically when xp doesn't matter anymore) and even so, has to burn all his stats points in his main damaging stat.
