This is what i wanted to post, but it would've been a bit too crazy to just flop it out on the table, so i had to ease you in.
The clan system...
I know the clan system is getting an overhaul change and most of the basic and fundamental stuff must be already planned out. But when i think of clans i think of clans from MMORPG's i've honestly never played one, but i was thinking of crazy ideas like a big clan bank system that is owned by the staff. The main reason of it's existence would be taxes, i.e. you'd have to pay a certain amount of tc monthly to be able to take part in clan events, which there should be more of. This way it would be a tc sink, and more of an activity drive from clans.
And maybe even warring taxes as well, where both sides have to pay a certain fee to be able to war, this way wars would be actually worth tryharding for.
Ofc this idea isn't very well thought out and there is a lot i mean a lot of problems with it, but when i thought of it it seemed cool enough to waste your time.
