Can I see this evidence please? Because im currently writing up a venatori faction review and there is no enemy on that faction which is vulnerable to fire, only resistant. There is 25 enemies across all 3 factions and you are claiming fire is the best because two of those 25 are vulnerable to fire? Did you also know that Despair demons have no armor rating whatsoever, so any physical attack will kill them very quickly?
Wait a few days for me to finish up testing, writing, editing, rendering and uploading each faction review and then make your own conclusions based on numbers and statistics, not what you feel is the best because reasons.
I'm not trying to be confrontational. I'm trying to have a polite conversation.
Also, I did say "I believe." That makes my statement and anything that follows it opinion. I'm formulating my own opinion. Also, evidence doesn't have to be empirical. Anecdotal evidence, experiential evidence: these are other types of evidence as well.
Since we cannot know what we face, then it is probably best to choose a rune based on what element has the least amount of enemies that resist it, or the most that are weak to it. Now, that may actually be lightning, or frost, but as the Venatori do not give me as much issue as the RT or Demons, I tend to base my assumptions off of that premise. Now, RT has resistances to lightning on some of its more irritating members, so I would instead prefer not to take lightning. Note I am using personal preferences here. Frost (to my knowledge) has bonus damage against certain enemies, but most of those enemies I do not have a problem with in the first place.
The reason I chose to focus on those enemies instead of looking at all 25 is that my trouble enemies are RT Knights, Despair Demons (yes, I know they have no armor, but fire damage still does a lot of good against them) and the DC. I don't have a lot of issues with behemoths, fear demons, rage demons, etc., because I know how to deal with them on my respective classes. I know less how to deal with the RT Knight and Despair Demon. And the DC is just stupid. Now, DC has no elemental vulnerabilities. RTK and DD have fire vulnerability. Ergo, I believe that fire would be the best. When empirical evidence shows me otherwise, I will take that under advisement, but I highly doubt that at any point is someone going to kick me from a lobby because I have a fire rune as opposed to a frost rune or lightning rune. And at no point would I probably be running perilous with someone like that.
I like you Penguin. You have time to put effort into this game that most of us don't, and I admire that you come here to share your findings and views. But, ultimately, this is a place for collaborative discussion. I'm not saying that you're wrong, I'm simply stating my opinion. If you disagree, then that's fine, and I will explain myself. If you still disagree, then we will agree to disagree.
