The gamble part is true i didn`t think in that way thanks. hmm about the Chat exp its more like people that love`s to talk to strangers would really do that by my self i like to meet new people talk to other people i don`t know. i have been i some Discord servers before like anime Discord for weebs. Its really active because they have the same passion but they ain`t talking about anime they talking about random things and have fun with each other. they made friends like i did to wehre i can by example play games with on cubecraft.
but I think your answer is correct everyone has his own ideas about it.
I'll break down why it's really unnecessary in 2 parts (unneeded for the current discord community + unneeded for the non-discordmembers):
1. Current Discord Community
They don't need this, because they're already active on there, no need to give them more incentive to become more active.
2. NonDiscord Members
They don't need an incentive to join either, because why would you want to give them one in the first place? The discord doesn't serve a functional/practical purpose, it's just a chill place to chat around in. Compare the discord to the forums, the forums are the place where the community can give positive and negative feedback on management's actions to give them a sense of if they're heading in the right direction, it serves a functional purpose, therefore, we "need" more active members on here.
