100 gems to remove level 4 embedded gems

[Legolas Bow of Athena]

It was put in to prevent players getting too overpowered.

I am aware of this but think about it, the impact of a lvl 5 vs lvl 4 gem is minimal. It is helpful but it's not like anyone will be supreme power from upgrading and 5's 6's and 7's aren't exactly easy to get even if you spend a lot. I don't think anyone has the coin to throw down for 6 massive diamonds. If they can afford 4,325 gems for a lvl 7 diamond then 100 won't be anything to them.

I'm looking at it from the standpoint of the mass population. If you win a level 4 diamond from boss fight or lab your going to want to use it, not only put level 3 diamonds in slots and wait a few months to build it up.
