I agree. I guess the best way we could use this thread is to state how the devs could make the game harder.
My suggestions.
On the hard mode, the mobs ought to be able to teleport you away the same way we do to them.
They ought to be able to sneak if we break line of sight to them (and not show up on the map).
Huntsman ought to have an abundance of special arrows and use them continuously.
The mages ought to dual wield wands.
The opp ought to be able to use loremaster on you to determine your weakest stat and try to use that against you.
Each opp ought to have large healing potion that it could use as soon as it is below 50% health.
