I legit feel like this is an unbeatable tactic

The enemy team built 5 guardian angels and I felt like i couldnt do ANYTHING. What could have I done better in the given situation ? The yasuo is untouchable for me if he is around his team because of his shield and wall. The akali... no comment. Her w + GA and zhonya... It lasts like 3 teamfights. The pyke had 200 armor and all he has to do to escape me is hit E and W.. The jax... well... self explanatory. The tristana was kind of killable, but we aint winning that game with me as the strongest member of the team dying for one of theirs. Im not to (with excuse) b*tch, but this tactic (building 5 guardian angels) actually feels really strong. You just seeing that circle on all of the enemy team players just makes you want to FF straight away.
