Mount XP: Please increase feed attempts

[Herby]

As it is, increasing mount levels need twice the xp of the previous level.
In short, to get 10 levels, you would need 2^(10 - 1) x mount's initial xp. (2^10 = 1024)

For ex:
Bear = 1000xp x 512 = 512,000 xp for 10 levels.
Feeding 5x a day = 500xp = 1024 days
Feeding 5x a day + 10 tames a day (150 gems) = 205 days
Using gems only, it would take 38,400 gems to get a level 10 Bear
(roughly costing $2740 in gold package rates)

Frankly, this is impossible to reach for anyone less than VIP 8 (VIP 8 requirement is 50,000 gems)
And this is only a level 10 Bear. Only an "average" mount.

Tynon, can we please have more options to increase a mount's xp?
Some suggestions:

- As a mount's level increases, the number of times of feeding per day also increases
- As a mount's level increases, the amount of xp per feed increases, as well as the cost.
- REMOVE THE FEEDING LIMIT per day, BUT increase the cost of feeding exponentially to scale with the mount's level.
