Currently pest control is a bit underplayed when it comes to getting things from the rewards shop, all people go for is the exp. It may be because the void sets have become tradable, but there is a good reason for that so I wouldn't like to touch that. I do want to suggest something that might get people to buy rewards from it however.
Upgrading your void set to elite doesn't seem too bad of an idea. Currently the normal void sets are regarded as trash by most people, due to the fact that elite now has better stats than the normal sets. My idea would be to make the elite sets untradable, but turn into normal sets upon death. Normal sets would be upgradable for pest control tokens at pest control at a price of around 1k tokens.
I understand pkers might not like this update, since they'll have to play pest control for their elite void. An alternative is to make the upgrade an item instead, this item could be made tradable so pkers can buy it and it might turn pest control into a viable way of making money.
Opinions?
