Try resting during Summer's End boss fight when things are attacking you...I'd rather take a pot instead of getting smacked around like a rag doll any day of the week. So yes, energy pots still have its purpose, just got to find them.
I just want an option to have older graphics...I don't like the new ones at all. That's why I play on Standard Definition, it's the closest I could get to Low Detail with RS2...
