I played against someone today fighting my way up to 1st. I could not beat him while he was defending his spot, every time I'm about to take someone of his team out they stealth and heal back to full. I could not focus on one target, my damage was spread almost evenly to all his characters. I think his other characters were Talia, Fives, Leia and Daka. Someone else in the top 10 beat him for me. How would you guys counter this? After this encounter I'm definitely sharding a Teebo up!
Btw the Teebo leader skill was something like 45% chance to gain stealth at the beginning of a characters turn and 25% chance to gain turn meter at the end of turn.
