Well, the thing is, when you say to adjust for the increase in population data, keep in mind that the population itself does not necessarily change. So when you have a means of being toxic being more freely used within the same population, of course there will be an increase in toxicity. So making decision to prevent that is not being unfair with regard to the population data, just a natural reaction to an inevitable outcome.
Specifically, the interaction being compared is grouped PVE content with GCD-based action system intended to kill enemies through an instance with other people via random matchmaking or selective party making. The fact that one community is more casual than another with respect to gear or any other factor does not change the composition of the overall community in both games having players with different interests coming together to play.Though in terms of social interactions between each game even if they are the same genre I would honestly have an easier time comparing gameplay elements cause the social experience at least for me differs greatly. Not sure what it is but the social experience even down to the trolls seem more unfiltered and things that public outcry here I do not think would phase the WoW community.
Though I am in the camp that while games may be comparable the community often cannot. Like I can compare game design philosophy between DOTA 2, LoL, HOTS the communities differ so greatly at least in my opinion that one cannot fairly compare the three. Same is fir me and FFXIV. Hope that makes sense. As an example I find myself far less crash in FFXIV then compared to FFXIV and more laid back I guess. Even my friends who do not play FFXIV but we use the same discord say I am like a differ t person.idk at least in my eyes something about each game draws a different vibe out.
In fact, you've said several times how you prefer what WoW has in terms of social interaction, and allowing parsing is one way to be more similar to WoW in that regard, so the comparison becomes more valid as well with respect to the effect within the community.
