What exactly makes it "circumstantial evidence" Your on a internet forum asking for advice and I am giving it based on my experience and facts. I have all the REMA except Redemption and I use them all. I consider myself a veteran DRK and I was just sharing my knowledge. Don't ask for something if you don't want it
The facts are
1. Torcleaver is one of the best WS at 1k TP especially now no WSD bug again
2. Even before augments Calad was one of our best weapon +50 VIT, low delay and triple damage make this so.
3. Calad got 10% Torcleaver damage aswell as 20 STR and 20 VIT even further increasing WS and melee damage
4. Other REMA that got upgraded dident get the same kind of boost due to poor WS tied to the weapon. in a zerg situation nobody spams entropy with anguta they use cross reaper for example, meaning the gap grows even bigger
The fact that spreadsheets don't take into account many many factors such as skillchain damage, use of JA's etc actually makes them "circumstantial" imo...
In fact if you look in Orestes post a few up from yours he shares a spreadsheet which you don't even need excel to quickly open in your web browser and see he has a comparison of Lib and Calad. Calad wins and that's without skillchain damage. There is your evidence
Also people talk like Liberator and Calad are DRK's only weapons these days. We have so many strong options... Anguta Cross Reaper spam is very very strong, almost as strong as Calad/TC Spam in a zerg situation. We have so many amazing great sword options that are not even REMA's! Apoc is amazing for solo/low-man. Ragnarok DRK is the only DD that can solo multi-step with a GS. DRK's are spoilt for choice really
