Everyone is ignoring Teemo. He's gonna be a boss.
1) This mode will be about speed. getting to unprotected nodes to claim them, getting to contested nodes to help win a team fight, getting to your own nodes to defend. Teemo has a passive speed increase, an active speed increase, and his shrooms will slow anyone that hits them.
2) He can stealth out at a node and make it look undefended, then rape someone when they come to BD it.
3) His poison will (I assume) prevent people from capping nodes as long as it's ticking. That means he can come in and hit you once and prevent you from capping for 5 seconds. he doesn't even have to stick around. He can use his poison and speed burst to stop 3 people capping and still get away.
4) Global taunt will make people stop channeling voluntarily to try for the kill.
