Not to mention, if the 6 hit Ragnarok is better than 5 hit Senbaak, and inferior to the 7 hit Ragnarok build, then the 7 hit Ragnarok would still be superior by simple logic.
I agree with the point you're making but it took me a minute to process the wording. lol.
I remember back when I was playing the discussions in war thread about hit builds for rag and ukko, and the ensuing drk ragnarok in legion discussions.
The strength of a build can vary depending on: what content you're doing (depending on if the seas of SE have made acc/att irrelevant / important this week for example), what a higher hit build brings to the table, and what a lower hit build sacrifices. The further complication is that the crit hit and relic ODD depreciate your melee phase less (white damage is less of a "liability").
Either way, ragnarok will easily pull ahead by using scourge while wearing all the new af+2.
