Spend Legend Trophies for Perks

I feel like the game will fizzle out if it is just a non-stop addition of higher levels. Maybe it would be fun to introduce a different aspect to game play for those who are in the Legend League.

For example, the ability to spend collected Legend Trophies for perks (that only work in the legend league.)

Those perks would reset at the beginning of each season, just as our trophy count is reset back to 5000.

Here are some perk examples:
Buy an extra giant bomb for 50 collected trophies.
Increase your camp size by 20 for 200 collected trophies.
Increase your spell time by 0.5 seconds for 100 collected trophies.

You get the idea. Such a system, would give Legend players more incentive to play. They would want to collect trophies so that they could spend them.
