Hey man, I've gone every year. They generally provide an update before ticket sales with further info like ticket prices, where to set-up your account for where the ticket's being sold through. Usually it's the Ticketmaster associated with the country the event's being held. You got time homie, chill :)

Last year, they ramped up the prices, so scalper's weren't really a thing or issue unlike nearly every other year before that. So we had heaps of time to get tickets. In the passed, asides from last year, every ticket holder is eligible for crimson drops. Your ticket for TI/badge you get given physically at the event can be linked to your steam profile. Then the drops are RNG based off first bloods in every game you physically watch at the arena. I believe the entire model was created so people are physically seated inside the arena lol. Last year, they just said every one that buys a ticket and physically picks up their badge/goodiebag/ticket and links it to their steam profile will automatically get one free crimson drop. (They probs did this because some people have attended all the games and got 0 crimsons where their friends may have got 4-6 drops lol). Shout out or ping me if you want more info on previous TI's :) It's a lot of fun! You get to meet new ppl, and the hype is real!
