Posion is too strong
If 1 team has poision in the endgame they probably win, it is simply too strong. It is like having 9 hushes with Singed poisioning the whole enemy team himself.
Other than rangers i cant see what can actually counter poision, but ranger's seems weak. Olaf with berserkers is op but he actually needs to ult to before he is op.
When nobles was actually good in set 1 before being gutted it was actually harder to achieve than 3 poision.
