I think the question is what level are you...? Until you get 2-3 Runes yeah, you end up seeing a lot of 0-2 bonuses. My rune damage tends to be around 10% of my average damage.

And I think its based off of your weapon delay (like Store TP), Nureus. People have reported dual wielding weapons (which puts your delay around GS territory) yielded them with total additional effect similar to using a 2h weapon of the same delay. Technically you're usually getting less damage per swing and other factors (such as TP building speed) are what make it better.
