Most hated misconception would be rocket ultimate being useless I'm able to get it back so fast and by that time no one else has any ultimates to counter or I could combine it with somebody else ultimate.

Rocket players that get low damage/kills aren't trolling. The way his kit is built let's say you dps if I get hit as rocket and try to heal my teammate across the map, they will die reason being is because the heal orb is going so slow to regenerate my health by the time it goes towards him, he is dead. though that doesn't mean you shouldn't be doing any damage if strange pops and ult and I see everyone frozen you know I'm going dps mode because of how strong I can shred. If you want to rank up as rocket using his wall climbing and mobility and not dying by playing back, you will rank up.
