Of course Issei wouldn't say that Rias countermeasures were half-baked because Issei is a passive guy. He would praise his comrads over little stuff and always try to look on the bright side of things despite the reality of the opposite. I got nothing against Rias personally but she could've done better.

@Demonicjester01 I'm not denying Rias merit in creating the Balor form but simply pointing out that the difference is Balor form is a fusion of 2 people. Gasper uses just as much power as Rias. The form was made from her experience of Crimson Extict Dragonar and the information of Sairoarg using Regulus.

Balor Rias has unique abilities that are troublesome but her main countermeasures was just her defense against Dressbreak and Pailigual. Time stop wouldn't hold Issei long and teleportaion is something Issei has experienced with dealing with from his fight against Cao Cao. Her abilities would be very troublesome against a pure close range fighter like Fenrir which is why she had quite an advantage but Issei can fight both close range and long range and on top of that he has a longer time limit since she can't maintain her form for long due to stamina consumption. In short the odds were heavily against Balor Rias from the start. Even if Issei didn't have Nyuutron Beam cannon, his Dressbreak was already effective enough to exploit an opening. Rias countermeasures were half-baked which is why she was defeated so quickly.
