I've been playing this game for about a year now, and until now have religiously stuck to the idea that characters should be 50% of the deck. Recently however, I've begun tinkering with this formula: increasing the amount of characters in Stark, and lowering the amount of characters in Martell.
Assuming that most people begin the deckbuilding process with roughly 50% characters, when do you find yourself varying from this formula? Is it more based on what house you're playing with, or the style of play, or the gold curve? And how often does everyone vary from the 50% ratio?
