They are half-baked. Diodora for example was able to counter Issei's Dressbreak by sealing off the feelings of embarassment from his servants. Dulio used a video of Gabriel in a swimsuit to immobolize Issei and trap in a bubble. Nyx had a garmet that completely nullified Issei's perverted techniques and abilities. Rias knows how big of a pervert Issei is and she should've used that to her advantage. Even Sairaorg thought of a way to immobolize Issei by having Coriana to willing strip herself and it actually had a huge impact on Issei. Point is Issei's biggest weakness is women and Rias should've used that.
