Can we improve gem combination increases?
Why such poor increases when you combine gems to a higher level. Take Malachite for example 4 Malachite Simple Gems 4 x 35 Stamina points = 140) makes 1 Usual Gem (only worth 90 Stamina points), 4 Usual Gems (4 x 90 =360) makes 1 Unusual Gem (100 points).
Can we get at least 50% of the combined gems back? And decrease the percentage for each level of gem.
Example:
Assume we start with 50% for the first level of combination and decrease by 10% to a minimum of 10%,
A Simple Gem = 35 Stamina points
Combine 4 Simple Gems = 140 Stamina points x 50% = 70 Stamina points. Therefore an Usual Gem would be 105 Stamina points (35 from the Simple and the 70 point improvement for combining the Simple Gems)
Combine 4 Usual Gems - 420 Stamina points x 40% = 160 Stamina points. Therefore an Unusual Gem would be 273 Stamina points (105 from the Usual and the 168 point improvement for combining the Usual Gems)
Combine 4 Unusual Gems - 1092 Stamina points x 30% = 328 Stamina points. Therefore an Unusual Gem would be 601 Stamina points (273 from the Unusual and the 328 point improvement for combining the Unusual Gems)
and so on. You could even start with a lower value for the first level of gems.
Otherwise getting and combining gems is just too much work for too little pay off.
