...Little to no effort required for this, and little waiting, unlike scour tourneys...
Same could be said for fishing tourneys. Fishing tourneys are literally press button, wait, press button again, press another button or two, repeat. Not to mention bait and balls needed to fish actually being rather cheap and easy to get the credits for just from scouring.
So should we then remove scour tourneys and fishing tourneys because they're press a button and wait? Sure, there's an hour wait before scours come back, but they're still just press a button, wait for mon to come back.
Fishing tourneys have moderately high goals, right? And also, fishing is rather boring so there's that.
Scour tourneys have an hour wait and RNG involved, you could have an hour of all boxes or an hour of all nothings. There's little to no RNG involved with WT besides who you trade with.
And since when are all tournaments based on just RNG? Hatching tournaments aren't RNG based (or they aren't always). So why does RNG even need to matter here? All the OP is trying to suggest is another type of tournament as it adds something new to the ever repeating tournaments. I don't see the harm in it at all and your reasons for not supporting are a bit out there to say the least. Sorry to put it so bluntly. I just don't understand why RNG all of a sudden matters - when not all the current tournies are RNG based.
