You're indirectly stating that attack is useless compared to dmg with that statement.Yes but with the cooldown you are better off using a damage ring from hru. Attack effectiveness does have a plateu where you would be better off adding dmg and the 30% haste is useless as i dont know a single end game melee player who doesnt just hero haste@fury
It adds 100 damage to auto... Do you even have this ring?
Assuming that most end game players are heavy on dex, this amazing ring will add 15% of total attack and the 100 poison dmg skill.
To inflict more damage on raid bosses you need high attack, something hrung dmg rings do not supply.
Maybe in Morrigan everyone buys a lot of chests for hero hastes, but in most cases, people reserve those for raids and legit battles.
