I would like to see more tc sinking events
Examples:

More loterys. Shorter in duration and w/o the buy all tickets thing. 2 weeks in duration monthly lotery. 1 prize, a good pack or set of items. Easy to host and fun for players.

There are a ton of perma banned with lots of items. So the next idea is to use thouse items. Put them in a acc. People that send 5000 or maybe even 10000 tc to that acc get a random item in return. A bot is created that automaticly does that. The acc can contain all items in the game or random items found in magical sack. With 2000+ item it would be quite a gamble. You can get orc grip or void force. No qi involved so any player can gamble.

Mystery unique 3d item auction. A new item is created every 2 months, but tha players dont know what it is. They just bid on that mystery unique item. Official pinned post in items section.

And maybe use that red button every season or at least twice a year

Agreed 100%, we need more lotteries, even monthly ones.
