I don't think you realize this fact:
As you gain levels, the number of monsters (of a lower level dungeon) needed to level up, exponentiates dramatically.
A level 60 person in 10 days doesn't have the required gear to beat the dungeon quests lvl 50 upwards no matter how many coins they have (you can't buy plans of items anyway).
For example:
Level 39 Cursed Highland, each monster nets 621 xp.
If you're level 59-60, you would need 1.2m xp.
1.2m / 621 = 1932 monsters, 1932 stamina.
Stamina costs 100 gems for the first 125
50 gems for the next 25
Even if it goes on at 50 gems for 25 forever, the total cost just to level from 59-60 using level 39 cursed plains is:
[(1932 - 125) / 25] x 50 = 3614 gems + 100 = 3714 gems
It costs 3714 gems to grind from lvl 59 to 60 alone.
Assuming 10% compounding rate:
3714 59-60
3376 58-59
3069 57-58
2790 56-57
2536 55-56
2305 54-55
2096 53-54
1905 52-53
1732 51-50
1574 50-51
Total for level 50-60 grinding using lvl 39 cursed highlands is... 25097 gems!
This is a best case scenario, assuming the 50 gems for 25 stamina at the 6th try never goes up or ends.
Are you beginning to see now why going to level 60 in 10 days just doesn't seem possible?
EDIT: The screenshot above this post shows the low level gear the person has. With that setup, he would even hardly get to level 40 quests.
EDIT2: We haven't taken into account the TIME needed to grind. Assuming a conservative 15 seconds per monster, level 59-60 at 3714 monsters would take 15.47 HOURS alone.
