More Future Job Changes?

They don't have to be D&D prototypes, but are you arguing against classes actually having advantages and drawbacks?

Where? Where did I argue such a thing?

I said exactly what you quoted me as saying:
"There's absolutely no reason to tie classes down to D&D prototypes other than sheer laziness."

If every single class is a fast attacking mobile survivable class with a big hitbox, the game is going to get staler even faster.

I'd also like you to drag in the person who supposedly suggested this.

The problem with Power Guard/Reflection is that, ironically, the more heavily armored you are, the less damage you do (because the less damage you get).
I'm looking for an opposite skill, one that does damage based on your defense, which would allow a higher level warrior to just crush lower level enemies he walks through, like the tank he (supposedly) is.

So you want them to replace the current mechanics of Power Guard/Reflection?
Because there's absolutely no way they would give us two skills that deal damage on contact.
Take away the damage reflection from Power Guard/Reflection and all you have is Achilles which would clearly be repetitive and, thus, removed.
I'll keep Power Guard, thanks.

By the way, the only things that makes a tank a tank in gaming are the ability to withstand a great deal of damage and (optimally) ensure that they're taking damage instead of other party members.
So your definition is a little skewed since being able to roll over lower level enemies isn't a prerequisite.

On a final note, it would make absolutely no sense for damage to be dealt based on the attacker's defense for several reasons including the need to create an entirely new formula for one skill despite the fact that Big Bang was designed to simplify the game.
