A server round trip is a cost. It's not a good idea or a bad idea. I will pay the cost of a round trip if (a) it simplifies my life and (b) the cost is low enough. LiveView simplifies interactive app development (for me). Since I can run my Phoenix servers close to people, the round trip cost is usually very low.
