From my experiences, he was wrong, otherwise my RDM using Excalibur 119 and Eminent Dagger would not see Shantotto nuke with T5s for 1.8~2k when in Espial and about 400~500 in my level 99 Enhancing set. I do not mean just 1 nuke, I mean consistently hitting these numbers, something is determined by other gear, be it level, accuracy, I can not be sure but something surely is determined by more than simply our weapon of choice.
