Since the timeline has changed, the URL come much early than expected, Ryuutemaru has evolved for allowing to Issei to use GR's power earlier, normally URL would have to arrive in 30 years, during this 30 years, Issei would have the time to awaken GR's power and he would have been much stronger than now but he doesn't the time anymore for awakening GR's power by himself so Ryuutemaru has decided to help him, and yes, Issei is too weak for the moment but it is not his fault. And yes, everyone is too weak, Azuka said himself that DxD members were too weak for fighting against future threats.
