dude, whens the last time you've seen a 100 man tournament with a gift card reward or something of that nature.
Yeah, stuff like QuakeCon and other stupid **** where a lot of people forfeited and didn't take seriously, where like half the entrants are random *** people who enter as John Stafford or Abdul E. Rahmen IV, like literally entering with their real names. or if its at a con where people enter as like Cloudstrifehero777 and cutechocobopieXX and ****... hope you get my point
generally the overall skill pool of a big tournament will always be relatively bigger than a small one, therefore making players take it more seriously.
basing it on prize would result in problems like one city getting less points than another just because the TOs choose to use a lower entry fee. Some TOs might purposely set their entry fees high just so they themselves can get more points or he's trying to help his entire city be higher.
About losers bracket. I dont know about you but everytime I see a hobo bracket, I see gnes, razer and trela run a stampede over the bracket, it doesnt seem to me like there is a motive to go to losers bracket. Your example, ive never really heard of anyone who does that, and even so, its not logical.
If you want to conquer a tournament as fast as possible, you **** the winners bracket. Less matches that need to be played = less risk of losing.
There is a pressure in losers bracket, but there is also an equal pressure in winners to stay in the luxury lane and away from danger. Some people even play worse after they're out of Winners because they're demoralized.
