Raid Tournament: tiered options?

Random idea hits me as I’m sitting on my couch.

This isn’t so much a novel thing but something to make the raid tournaments better imo.

Let’s have a tiered raid tournament option similar to the 3 levels in the event quests. “But we already have that” you say. I’m suggesting weekly separate 3* - 4* - 5* raid tournaments. During the opt in phase you choose which one (AND ONLY ONE) you want to participate in. This benefits newer players who probably only have a team of 3* heroes maxed and once you get further along maybe you want to try your hand at the 4* raid tournament and so on. I may be wrong about this but the way I understand it when you set your raid tournament defense you’re supposed to only face players similar in power to you. I think separating the tournaments out by star would better ensure that we are facing teams similar to our team.
