Here’s a hero suggestion 
I hope we can discuss if the hero would fit right in the roster or would it be too op. Open to opinions and suggestions!
Role: Damager.
Position: Front.
SKILLSET
White Skill: Submerge
Tick-Tock submerges himself underwater rendering him untargettable for 8 seconds. On top of getting an increase of x normal damage (scales with level), all attacks done by him while in this state will always land a critical hit.
Green Skill: Bite (Normal Damage)
Tick-Tock chomps down on a unit that is near to him dealing x normal damage (scales with level) and silencing the target for 6 seconds. If this ability dealt the final blow to an enemy unit thus killing it, the cooldown is refreshed and Tick-Tock the Crocodile will immediately use it again.
Blue Skill: Hard Exterior
Due to Tick-Tock’s formidable skin, he is granted an additional x armor (skills with level). He also gains the ability to reflect 20% of the damage dealt to him back to the attacker. The returned damage bypasses all resistances (except invulnerability) and deals true damage.
Purple Skill: Joy of the Hunt
Tick-Tock, being a predator, enjoys in playing with his victims. He gains an increase of x normal damage (scales with level) everytime an enemy unit is defeated. The bonus only lasts for the current wave.
