Disadvantage small amount gem usage

[metroickha]

To finish a building with 1 hour and 15 mins remaining costs 23 gems. (0,3 gem per minute)
To finish a building with 21 hours and 25 mins remaining costs 233 gems. (0,18 gem per minute)

Why is the difference so big?

You already get more gems per money spent.
But if you are a small amount gem user, then you have this disadvantage.

Money is earned, equally. I understand it's a business concept to give more gems per money spent.
But after purchasing ... shouldn't gem's worth be the same?

It is pretty much unfair for those who spend 10 times 23 gems to finish just 750 minutes.
And someone else spend 230 gems to finish 1260 minutes.
While they both spend the same amount of money to gems ...

I don't think minutes per gem is proportional

I don't think minutes per gem is proportional

My English isn't that well. I do not get what you mean.

What I am saying is:
- I have one tower 40 minutes remaining that costs 13 gems. (0,325 gem per minute)
- I have another tower 1248 minutes remaining that costs 226 gems (0,181 gem per minute)

If you spend 10 dollars for 1000 gems, and I spend 10 dollars for 1000 gems.
Why should there be a difference in spending the same amount of gems?

You spend 20x13 gems to speed up 40 minutes (800 minutes saved).
I spend 1x260 gems to speed up 1248+ minutes (1248+ minutes saved)

Plain and simple

If you are in a hurry it costs more.

Like fast food get it now and hurts you later

a lot of gemmers buy them don't learn how to play and leave the game quick,

Supercells favorite kind of players.

His point is that gems to minutes saved is not proportional.

If you get something earlier on (when there are days left) you get more bang for your buck, but if you wait for a while and then get to finish it when there is only a couple of hours left you don't get the same bang for the buck.
