Please buff Khagan.
Khagan has no chance against many 5* heroes because its mana speed is slow and his damage is too low. Only 305% to the target and MINOR damage to nearby enemies. Yes, his has good buffs effect, but is only to himself and nearby allies.
So my sugestion is to change some details and can be ONE of them:
- Slow mana speed to average mana speed and reduce 5 turns mana buff to 3 turns.
- 305% damage and minor damage to nearby enemies to 310% damage and nearby enemies (no MINOR).
- 305% damage and minor damage to nearby enemies to 400% damage and minor damage to nearby enemies.
As you know, today you are launching too many strong 5* heroes and some of them have PASSIVE effect too. So I think you should buff or adjust some 5* regular heroes.
