Wichtiges » Most important role in gold?

Hi,

In a group of solo queues, what role is the most pivotal to the team's success?
Assuming the comp is fairly standard. If you think it depends on the map, then
please let me know which ones are more dependent on what role.
Please help.

I didn't find the right solution from the Internet.
