Just a little idea. I think if you're spending as much money as someone like me I feel like there should be more perks... this is my personal opinion, perhaps others will disagree with me, or maybe I'm just wrong. Please try not to be biased especially if you play for free. I made this list so that you'll only get the good perks if you're giving an arm and a leg to play.

(Also if u do implement this, you should reward current supporting players accordingly )

100$ give them 1 or 2 power kits (either 10,000 or 50,000 or even something in between) and a couple of gold boxes would make sense

250$ 1 or 2 power kits + premium acc for a week + some gold boxes

500$ 3 power kits (10,000 or 50,000) + prem. acc. for 1 month + 1 or 2 ultra mythical boxes

1000$ +
5 (or more if you're feeling generous) Power kits
prem. acc for 2 - 3 months
3 - 5 ultra mythical boxes

1500$+
10 ultra mythical boxes and maybe some gold boxes
5 50,000 power kits
premium account for 6 months

Notice that the rewards increase exponentially with the more you pay. This will serve as an incentive for people to buy more tokens.
I feel like with even 1000$ you don't get much in this game. In other games I've played when you spend large sums they give more than just in game currency (in this case tokens). Let me get some thoughts. We can play around with the numbers and rewards ofc. I gave what I believed to be fair numbers, especially for the players that spend large amounts of money. I believe they should be getting more.

Lol, I just feel like even 1000$ doesn't get you much in this game. I feel like other bonuses would be nice. Maybe I feel this way because 90% of the money I pay goes to worthless mythical items. :/

If the items were more balanced and you didn't have to pay so much then I might think of this as ludicrous.

It still does serve as a good incentive to make people want to pay more.

Bumpppppppppppp.
