Tinker discussion - Your opinion?

[mooneye]

It is true that good players can play tinker well. They can manage gold and know when to switch other tanks. But for 95% players who used tinkers, they do not help the team but frustrated teammates.Usually the team with one or two tinkers was destined to lose at the very beginning if the other team has smart players to push side lanes.

I think we can have it in qualify games but remove it from league.
