"Pretty sure it was mentioned if one of those attacks landed on Issei, it would have put him down if i remember correctly."

I don't recall that being stated. Granted it would've did some damage to his armor but considering her attacks couldn't even put 80% Fenrir down than I doubt it would have put Issei down.

" would like to mention another strength of rias is her strategy."

Not really, Rias strategies has always been stright forward and head on. Sona even mentioned that Rias tactics are naive because she relies too much on her team's strength. She likes to overpower her opponent and while that can sometimes work, it also can lead to many mistakes.

"she try to fight them a end up becoming to exhausted after a encounter instead of sticking to what she should have done in the beginning and gang up on the king."

Rias has never done something like try ganging up on a king. In volume 2, she tried fighting 1 on 1 against Riser, in volume 5 she wanted to fight Sona in a 1 on 1, in volume 10 she and Ise fought Sairaorg and Regulus separately, in volume 23 she defeated that ultimate class devil in a 1 on 1 after he was wounded, in volume 24 she let Crom fight Vali in a 1 on 1, in Shin Volume 2 she fought Issei in a 1 on 1.
