About Elemental wand

The supporting class isnt stronger than AMs. Only they're full screen attack is more efficient than an AM because of the current maps available.

And 99% of mages spam said full screen attack to train.

Once Arch Mages get better maps things will change, but it's not something to obsess over.

135% stronger (more like 120% due to the base attack difference), 200% more expensive. Maybe when attacks were 50 MP a cast that was a good trade-off, but not 3500.

And I'll say it again - these staves have helped AMs regardless of there being a elemental bonus on it or not! AMs can now be much stronger than what they were before.

Suppose, for some ludicrous reason, Nexon decided that everyone in the game would have a permanent +10% damage boost. Yay, AMs are stronger than they were before.
Strength is relative.

Finally, the same thing goes, if you wanted a character thats easily accepted into bossing/parties then a bishop would have been a wiser choice. Only one job of each class is usually dominant of getting chosen into parties.

I wanna revise that a little...
"If you wanted a character that's easily accepted into bossing/parties, levels faster, is cheaper to maintain, and does everything in general better, then a bishop would have been a wiser choice."
That's pretty much how it stands right now.
