I was thinking while playing, that it would be cooler if i was even weaker than i was now, so what about an option(much like the hardcore option) that makes me 50% weaker? 50% less damage, 50% less armor, 50% less hp, and if you die you have to run back get your stuff, but you get double the loot to compensate.
The double loot would be disabled if you group up, and your armor/hp/dmg values would be sent back to how they were normally, and when you leave group it would be back to your 50% weakened state. If a person not under this state help a person in the 50% weakened state kill mobs, the loot drop would be 1x rather than 2, to prevent abuse.
