Issei has become incredibly overpowered beyond belief. His Psuedo DxD G is far stronger than Rias (Forbidden Invade Balor The Princess). How may you ask? Issei was able to beat Vidar (enhanced w his boots and midgar armor). That's a big deal because in that state, not only is Vidar top 10 level but also much stronger than a prime Fenrir. Rias in her Balor form couldn't beat a 80% Fenrir while Issei in his Psuedo DxD beat someone who is much stronger than a 100% Fenrir. Right now Issei is top 10 level. Futhermore, Issei can now summon Ddraig so imagine Ddraig and Issei teaming up against Crom Cruach? The answer is so obvious but Ishibumi wouldn't make it that easy and would have Issei alone fight Crom.
