New Ragnarok Classes - Found

[Buttercup]

You left out the Slashielder - A shielder that gets so impatient for the round to end that it starts to slash with its feeble one-hander and inevitably gets killed.
                                          - It has a very low drop rate, particularly on the mixed waves when one commando is as good as another and he isn't tomed in.
Items of choice: Fang of Fenrir, Royal Shield, and a resurrection tome to be used when the slashielder is needed on a challenge/boss wave.

You might as well just change the name from slashielder to diamond_drop.
