Illuvium is a pretty complex game and I don't think the average viewer/player can easily see and pick up everything that the players are using during tournaments. Something that would be helpful is a RSI bar at the top of the screen that shows who is in the lead very quickly and simply.
I think as a viewer, you might see one side placed a full board of illuvials and the other side might have only placed 6, but they've got a ton of mastery points, a couple evolution tokens, and a couple augments they're waiting to use. In that case the RSI is closer to equal than initial glance.
I think something like this would help contextualize what's going on for a viewer which makes it easier to follow and ultimately more engaging and exciting when you know what's going on. Obviously casters can supplement this info, but they might not always be talking about relative strength and sometimes a visual is just easier to follow.
