Let me begin by saying, the gift a sub thing was absolutely amazing. But, I have friends who can't come to twitchcon simply because they can't afford a 3 day ticket. I think that Twitch is about building a community, and allowing friends to hang out with other friends in a small area. I think by gifting TwitchCon tickets, you can:

1. Encourage people to come.
2. More people at your event.
3. More exposure.
4. Building a better community.
5. More people to buy your merch.
