I feel like Murky has far too much going for him. He really is not fun to play against.
Put Murky’s ressurection timer on a cd. If the cd resets he gets his 8 secs. But if he dies while the cd is on, his death timer doubles. With each death the cd refreshes and his death will double until it is normal time, the cd falls, or his egg is destroyed. This would stop the agressive suicide Murky from being so irritating and oppressive. The cd wouldn’t have to be long or it could have an effect like hero and minion kills reduce the timer.
Just an idea. Open to other ideas.
