I agree, Renly would have been an awful king. He would have wasted even more money on tourneys and feasts, he would leave ruling to scheming fucks like Littlefinger, and his kids would probably be the same. One of the many things i love about Stannis is that I'm fairly sure that guy would drill his son into being a good king. You know, if he ever had one. Renly should have just been Stannis' propaganda minister. That would have been awesome.
