The "tank huge amounts of damage" thing has annoyed me going back to the old RPG games on NES and SNES. How do we make the game harder as the player progresses? Give enemies more HP and DMG values. Ok, how does the player combat this? Have him aquire levels/skills/equipment that increases his own DMG and survivability to restore things to the same balance they were earlier in the game. Repeat ad nauseum. Some variations restrict the player enhancements to DMG so they're forced to chip away at enemies in long dull fights. Others restrict survivability, which tends to result in shorter, more random fights, while others allow near infinite enhancement, but lock it behind boring, redundant grinding.
