My only issue with tournaments is that there is no way to level up the characters that we unlock. So I say either add characters to Hard Nodes/Cantina right after the tournament so people can finish them. Or have more tournaments with the same characters so people can finish them. It looks like they might be going that route with Jyn which I'm fine with but we need a way to finish the characters!
I have had Chirrut for a long time at gear 11 but no way to get him more stars so I basically wasted all that gear.
Also 1 day tournaments are a must! The multiple day tournaments take WAY to much time.
