My feelings on this is like what Sansa said to Littlefinger in the episode The Mountain and the Viper as to why she helped him. Actually she didn't say it. I thought she said "Better the devil you know than the devil you don't know." Littlefinger said "To gamble on the man you know than the strangers you don't."
We know this world and this system, but we don't know what things will be like in the new system. We just have painted pictures.
