What do you mean what else ? what other thing is there? hats, gani items, furniture...? honestly that's the fair way to go about it.
What if you received tokens, and have a store of items and you were able to gather as many as you want for whichever item it is you want. New items of course, we dont want to ruin the rarity of old items/hats.
because the idea of gathering enough to have your own gfx uploaded would ruin towers(hats/morph). So I guess a better way would be to gather and save up your tokens to use like the old holiday token shop whether you wanted to use them or not and wait for the next round ( 1-3 item month change?)
a fun little reward for the easy quests can be gathering pieces of a puzzle and slowly completing your portrait image that can be placed in your guild house.
be able to use those tokens in a mini-game house room, like opening the circus by adding events rooms ( like ice race, chance, survivor - all the original events in there) it would give a chance for those who are not capable of getting into the warps and then losing to the already expert events winner since they can find them all the time. ( a normal group of 30-50 depends which event would be able to go inside and every time you would have to wait your turn or decide which one you want to participate on )

*have to go right now but if more ideas pop-up i'll come and write them down as well
