It's called shocking execution and it is a daily that ignores defense, also its damage scales with how much hp the target has remaining. I also don't understand what you mean by rogue daggers having same damage as greatswords.
I've seen cleric bots that run to the same exact spot on the map, then engage in battle. Others just stand at the campfire and occasionally jump to avoid being afk kicked.
The only rough AD I get is from praying and the pvp quest. I do make around 200k(total) selling pvp items in the auction house, though the prices are constantly dropping.
