Most of my rounds are just a battle of patience. Going first is hugely disadvantaged because the opponent can calculate what they need to beat you. The aim of GA is to gain as many points as possible, not just get enough points to win. The battle of patience is strongly affected by what timezone you are in. Those who are asleep during the end of the round are disadvantaged as they cannot play the patience game.
Just to give an example; I see my opponent has failed multiple times against my Darth Revan, meaning they are not going to clear that zone. I can calculate and choose to use the Tier 1 teams I have prepared against Darth Revan (such as Jedi Knight Revan or Commander Luke Skywalker), on other teams to ensure maximum banners. If I couldn't see their progress, or their failures against my Darth Revan, I would use those teams to try beat the opposing Darth Revan. This has two outcomes; one is that I beat the darth revan and get more points, or two, I lose to Darth Revan, and get less points. There is a risk vs reward decision making that is taken away if you know your opponents progress.
