No, this topic isn't about which three classes to use to beat their dungeons.
Now, as we all know, unlocking these 3 classes require that you beat 3 Vicious dungeons 3 times with different classes. This is by no means an easy task (please no talk about resist abuses or whatever) and probably won't ever be (since the base intention is to beat several Vicious dungeons multiple times)
However, currently as it stands, the monster classes aren't really that great. Vampire is basically considered to be the SUCKIEST (haha, see what I did there?) class and both HD and Gorgon are still only really around mid-tier.
In other words, these classes are...http://tvtropes.org/pmwiki/pmwiki.php/M ... ghtsReward
Now, don't get me wrong, I'm actually okay with the HD and Gorgon power level now. If they were comparatively easy to unlock like the Alpha version then they would probably be a fun diversion but after grueling through those Vicious dungeons it kind of takes a lot out of me to want to play them again.
Anyway, since I don't think you should raise those classes power levels to superhuman levels, how about making them easier to unlock? It's more fun to actually use those guys in an actual game rather than as post-game content.
The old quest for them right now can be changed to unlock 3 new items that are good for them or something.
