First and most important:
100 gems to remove a perk is way to costly for the following reasons. You might and probably will get the same perk again. The chances of the next upgrade being successful goes down, and the cost of pearls go up. This means if you get a perk you don’t want and remove then the entire upgrade process is negated.
Fix: Lower the cost of gems to remove a perk for sure.
When a perk is removed the cost and chances of success should go back by one level. Even though you have to upgrade a stat to get the 3rd perk, paying gems to remove it justifies this.
The cost for upgrading items is heavy compared to how many pearls a player can bring in. The high cost was supposed to be because we can now get pearls through the Blacksmith. Well you don’t get many pearls from the blacksmith and it takes way to long to melt them down.
The chances of an upgrade working is low from the start. The cost and chance of an upgrade working is ridiculous.
Everything about the BlackSmith is tailor made for paying players. After offense was completely nerfed and defense was completely buffed the BlackSmith is the only way to compete with paying players.
Fifth: Useless perks. Adding toxic clouds as a perk is just a way to make us spend gems.
