Since common complaints on some of the previous posts include unappealing prizes and lots of time sitting in line, you could fight these two problems by asking out some questions with small TC prizes in regular intervals of time.
The content on the questions asked could range from: forum/in-game rules (neat benefits for the whole community if those were more generally known, specially considering a decent part of the in-game community isn't familiar with the forum or with rules in general); Toribash History, like culapou's trivia used to be (it could make people look through the forum for the answers, making them both more used to use it and more attached to the game/community because of the more in-depth knowledge they would have about it); or even common topics like basic science and whatnot (14 year olds learning real-life-relevant stuff is always yaaaaaay because educated people are cool?:D?).
People also seem to be complaining about grumpy hosters. If you're grumpy, don't host. If that leads to less tourneys being hosted, recruit more people, enough people to cover for each other's grumpy-ness.
For those saying that GMs have lives and they have the right to be grumpy: yes, they can be grumpy all they want, but that's not an excuse for them to provide bad tourneys, that's a reason for them to not host tourneys. If you're grumpy, don't host.
Lastly, I do agree that the tournament actual prizes aren't very appealing, but for the prizes to get better you'd have to cut down
alot on the 500-tc tournaments and such, to maintain the ratio of generated items+TC per unit of time and not sink the economy further. I'm actually in favor of this, but I don't have any in-depth knowledge on the auto-tourneys overall impact.
----End of GM-directed part of the post----
For everyone asking why the GM's can't generate cool items for every tourney:
-With more frequent good prizes, said good prizes become more common among people.
-When something becomes more common, it has less value. Imagine a trading card/baseball sticker, or anything collectible of that sort. If all the kids have that card/sticker, it becomes less cool, and you would give less valuable cards/whatever in trade for it.
-This would eventually lead to TC being less valuable (you need to think about it with the logic I used in the example above: "people have tons of it so it is less valuable)
-If TC becomes less valuable you wouldn't buy it on the official shop, because why buy 10000 for 10$ (or whatever rating is used now) if you can just win a tourney and get a 15k prize?
Note: If the shop sold more toricredits for the same amount of money, items would get too easy to buy and people would have less need to buy toricredits. If you'd raise the items prices proportionally to increase of TC per $ sold on the torishop, you'd have constant rises on the item prices, which is pisses people off.
-If hampa doesn't get any money, he has to spend time trying to get money in other ways and forget about Toribash, and that'd pretty much be the end of the game as we know it now.
tl;dr for this last part: awesome prizes would ruin the economy and hampa wouldn't make enough money and big sad face for the game's future.
