Good day to the development team. In the latest patches, you have finally started modifying skills. I hope you will continue to do so, as there are still many candidates for improvement. Several years ago, I already shared my thoughts with the team. Now, I will update the list to reflect the changes that have already been made.
I know that many people are currently writing about skills, but I ask you to spend a few minutes of your time. Perhaps my suggestions will inspire you with new ideas.
Ballistics. Artillery improves the combat characteristics of machines. Ballistics could increase the hit points. The old property related to catapults should remain, but in addition to it, it should increase the health of all combat machines by 50-100-150 percent. The percentages can be even higher. A cannon will be more effective in final battles if it lasts longer. When machines are used as a living shield against monsters on the map, they will also last longer.
First Aid. After obtaining the skill, the tent heals 2-3-4 times more health. At the advanced level, it begins to remove harmful spells. At the expert level, the tent's actions become area-of-effect.
Trainability. When upgrading a hero, not only increase experience but also allow them to choose the skills they receive. The basic version should allow choosing skills of the first level: attack, defense, strength, knowledge. The advanced version should allow upgrading any of the skills already obtained as desired. The expert version should allow choosing any skill from the complete list at the next level.
Luck. Instead of simply increasing luck by 1-2-3, also increase the frequency of luck upgrades by 50-100-150 percent. You have done something similar for the new leprechaun units.
Keen Sight. All used spells of all levels are automatically learned. The skill allows you to obtain 1-2-3 spells after a battle that the hero has not used, including spells not for combat.
In all cases, I am providing approximate numbers. I think you can find more accurate ones. Thank you again for your work
