i don't necessarily think its a bad idea, but i don't think its that good an idea either.
to play devils advocate: people will "say" they're playing for the prestige of winning a ti but outside of envy (he's the only one that autistic) I don't actually believe anybody when they say that. they're playing for the money.
if every team gets a (roughly equivalent) big piece of the pie, what's the incentive for any team to perform?
last year newbee got $5,028,121 (46%) of the pool ($10,930,698).
if TI were to start today, the prize pool would be $13,243,203 and 1st place would get $6,091,873
if NOTHING ELSE, 1st prize winners are gonna expect at least as much as last years winners. if the prize pool reaches 15Mil (probably), and we want to give at least 6M to 1st place, then we can safely lower the % 1st prize gets to 40%, freeing up 6 whole percent to give to other participants
so where do we throw that money? we could give it to the 2-4th teams, but their prizes are already pretty big. is it worth it to give it to the sub-5th place teams? are they really deserving?
spoiler alert: probably not. they didn't win. this isn't your 6th grade soccer league where everybody gets a trophy just for participating.
the international isn't about crowdfunding esports teams so they can go on being teams. it's about the best teams in the world playing the best dota in the world. if they disband as a result, who cares? clearly they weren't in it for the dota. players that want to will find other teams, players that don't will move on.
my only caveat here is teams that don't have any kind of organization/sponsorship backing them won't be able to practice the way teams that DO have money in their pockets do. It's a double edged sword (rumors that organizations like na'vi shoehorn players into less-than-desirable contracts and take obscene portions of prizemoney) and i want to see the scene grow, but not at the cost of depriving deserving teams their well-earned winnings.
