People have been multi boxing WAY before player population increase. For example My "endgame LS" in 2016 which cleared the hardest content before everyone else had 8 real players and another half were alts.
You make it sound like multiple box is a trend that started recently and population increase is the result of it, which is false. People don't suddenly "get into multibox" recently. They've been doing it since forever.
Personally, I run into new/returning players way more often than alts/bots.
Keep in mind my statement was just "I wouldn't be surprised", Im not asserting it as an absolute truth, simply just my own personal subjective experience on Asura.
Which is why I simply said "I wonder", I think your points are pretty valid too.
I dunno, it really does feel like multiboxing is
much more prevalent now than it was a couple years ago.
Before sure, I would see the occasional train of characters run by here and there.
But now, standing around in some zones, its pretty much constant in highly populated zones that there are
multiple different trains of characters running around, doing actions at the same time, wearing identical gear, etc etc.
I really will say, and this is subjective though, Id estimate theres about 4 or 5 times the density of multiboxer trains roaming around than I remember a couple years ago.
But thats just me.
I mean there's arguments to be made that bot accounts got crippled by the sparks changes, I have zero idea what bots are doing now that they cant make money sparks farming. Like there's some random basement team in china or korea now that has like 80 FFXI accounts (Dragoons I think they were?) unable to print money like they used to.
The hell they gonna do with all those accounts now?
I started tri boxing, 6-7 years ago, I added 3 more this year. I would say it's a pretty decent possibility that those population spikes are more alts. Not that all of them are, but it is a pretty big portion. On that same note, I have seen much more new/returnees in that same amount of time join my shell. I would put the number at 2:1 new players compared to alts. In my shell, maybe 4-5 alts total have been created since spring. Seen a good 10+ new real bodies in that same stretch.
It certainly is a trend that there is a constant slew of "Im coming back after 10 years, FFXIV is boring, what do I do?" style posts on the FFXI subreddit.
