Mechanic recently received skill changes in kRO. Arm cannon now has increased area with increase in level, and maximum level is now at level 5. Blacksmith buffs can now be used while in MADO. However, arm cannon also received a relatively important downgrade, addition of cooldown with the skill. 0.15 s at skill level 1 and 0.65 s at skill level 5.   I think these changes are good, but still not balanced. Other jobs' damage can easily reach 1M+. What can be the item changes that we need
