I'm not sure it is possible to get A rank or higher

I have won many star guardian games playing solo. I carry the hell out of others by playing Soraka and keeping people healthy while dodging more bullet spam then Super R-Type. I've had games where I died less then 3 times on multiple occasions. It never matters. The highest I can reach is B+ rank. The score required to get A or higher is set at such a ridiculously high number that it requires the entire team to play perfectly. If 1 person dies it pretty much guarantees that the A rank is lost. Also, even if no one dies because they play safe they will not get A rank because they take too long to kite out enemies.

Riot, I hate these missions. I cannot do it. I don't feel that I can do it. I give up even though I really want to unlock the ward but I just can't get that impossible to reach A rank without some sort of crazy premade 5 man vet team with dodge skills, mechanics, and kiting skills on faker's level. This is ridiculous. So I end with this...

TONE THE DAMN SOLO MISSIONS DOWN!
