Make a new payout multiplied EB where it has an item to unlock, same idea as the tusk/seal, but instead make the new unlock item something that you can buy in the shop for *one nob point* and the bar to open the EB instead of needing one item (like ROW/HTE do) it needs 25 of them. That way one single person can spam all 25 items, or 25 people could each use one item, or any combination in between. And just like with the tusk or the seal in the existing fancy pay-multiplied EB's, make it so the item usage gives you gold for having used it, maybe $100m or so. And just like with the tusk or the seal, make it so this new item is one that can also drop in the EB that this new one is based on. Do it for a tier 2 or tier 3 EB. Make it pay somewhere in between what ROW and HTE pay. That way the top spenders are still gonna stick with HTE, so it doesn't cut into that revenue stream too much. But make it more affordable than HTE as well, like I suggested 25 items at one nob a pop.
Do you know what trolling means? This isn't trolling, this is using this forum for exactly what it was created for, to make a suggestion to the devs which is actually a good addition to the game.
