So sorry for my delay here. Discord is definitely a great app, and the integration does make it easy for you to manage access to your patrons at different tiers.
A couple thinks you should know:
If you’re livestreaming or want to host a video chat/ screen sharing hang, you’re limited to 10 attendees on Discord. Here’s more info: https://support.discordapp.com/hc/en-us/articles/115000982752-Screen-sharing-Video-Calls
What exactly are you hoping to do with your streams? If you’d like folks to ask questions, and expect a smaller group, Discord might be the right place to host it. However, if you want to have larger events, I suggest Google Hangouts, since it’s relatively ubiquitous, or Zoom, since you can easily record sessions, and there’s a great chat feature. How often are you thinking about hosting streams? Do you want chat and streams to happen in the same place?
Patreon also has integrations with YouTube Live, and Crowdcast. Crowdcast is the service I used for our web class, and it’s a bit more robust. You can host larger groups, provide chat, record, and invite folks up on screen to talk, but it is a paid-for service. Being a creator provides you a discount, but it is something to consider.
Would love to hear more and help figure out where the right place to host this will be!
