Actually it only took Issei four months to overpower Rias because he achieved his Balance Breaker. Kiba stated in Volume 7 that him and Issei were the strongest ones in the peerage. These are the qualities of a king in my opinion:


 * Leadership: ​Does the king have the charisma to have his servants follow behind him? How well can he inspire his servants?


 * ​Ability to gather servants: ​When becoming a king and getting your evil pieces, devils go out and find potential servants. Can they find servants with unique ablities? Are they able to have a peerage with a variety of unique abilities? How good are they at finding talent? And just because someone like Riser has 8 single pawns and doesn't have someone who is worth multiple pawn pieces like Rias, Sairaorg, or Sirzechs who are exceptions doesn't make him lame or weak. Not every devil just runs into a Longinus possessor or a powerful dragon. That's not normal. If Diehauser had 8 single pawn pieces then what would people think? Devils go out and find potentially strong servants especially if they decide to participate in Rating Games. Whether they find the talent or draw it to them. Rias and Sirzechs have an unnatural talent in this. I would say Rias even more so since she gathered all her servants in 5 years, Sairaorg is strong in this trait although not as strong as Rias and Sirzechs.


 * Power: ​In Rating Games, the king has to be defeated for the opposing side to win. Even in most Rating Game variants, that still stands. So the king should be powerful and be able to stand on their own. In nearly every case, the king is stronger than all of those in his peerage. Rias, Sona, and most likely Seekvaira are the only exceptions we've seen so far. Rias is because of the point above I just mentioned although she is very overpowered but the servants she gathered are overpowered as well. A king should be very competent in battle. Because there will come the time in the Rating Game where the king will fight the other side's king or the servants. So the king should be ready for that when it comes.


 * Strategy/Tactics: ​Now it's not necessary for the king to do this or for the king to do this alone. The king can have a servant that's an excellent strategist/tactician. Because no matter how strong your team is you'll have to rely on some form of tactics and strategy. Because there will come a time where you can't beat your opponent with pure power. So it's good to have a plan in mind or predict what your opponent will do and create a countermeasure for that. Tactics and strategy can render power utterly useless at times. The same can be said vice-versa. I say it's good for the king to have at least some understanding of tactics and strategy. How to utilize the servants and their abilities in the best way possible, how to use the rules and restrictions to your advantage, etc. There are so many Rating Games and so many possibilities. So there's never going to be a lack of strategy and tactics. Sona Sitri, Seekvaira Agares, and Rudiger Rosenkreutz are good examples of this.
