Listened to the Shattered Order podcast from last week and they had a great QoL idea re: raids.
Once a player has a 7-star Han Solo from the Rancor raid and/or 7-star GK from the HAAT raid, then a new challenge should open up for each instance, a Rancor Raid challenge and a HAAT Raid challenge.
The Rancor Raid challenge could be scheduled 3 times a week and the HAAT challenge 2 times a week. Each one would only be able to be done 1 time per day its open and basically it just randomly gives you a rewards bundle that includes credits, guild currency, gear and toon shards.
The raids could still be launched with tickets but only those who have less than a 7-star Han Solo or GK would need to participate in the raid to get rewards. The others could opt to do so for fun, but would get no rewards.
By doing this, advanced players are no longer required to do the raids, but can still get rewards for them.
