standard mode online ?

is there any info how many people plays on standard mode? just want to know if it worth playing there or not

I dont know if you can find that info.
I doubt many people play there.
The one that do play either SSF or pseudo SSF since the economy is probably non existent or completely wild.

If you want to play trade i think playing the abyss league is much better. Even tough the economy is already rough there too as i understood.

But you will find people to play with there to make a party or so if you like multiplayer more.

you can't get actual numbers but if go look at the trade site and swap between standard and league for something and set the timeframe to like 12hrs you'll see how many less ppl are selling it in standard if any at all

Sorry to dodge the question a bit, but why do you ask? What is your interest in playing Standard? What are your actual concerns? What would make it worth playing there? What would make it not? Especially w/ Async trade, I'm not sure how much pop count matters at this point. But, again, please clarify what you are looking for in Standard vs League.

Some people play Standard to get the "perfect" character. Even then, they often still play Leagues to get certain items for their build easier (cheaper), or even to get certain items in a League (particularly end of League when people are dumping their gear/inventory) so they can sell them on Standard to fund their character.

If you simply are turned off by the League resets, then just play Standard and ignore League exists at all. If it's fomo for League mechanics, well that's just the way the cookie crumbles. League mechanics get rolled into Standard after the League ends, but it won't be as common as when it was the League mechanic and it may be adjusted in some way. It's a bit of a ways off, but I'd recommend starting a new character in the next League then just stick with it when it gets rolled into Standard.
