I feel like this should be something part of the subclasses so other classes can't poach it. Stellar Rush doesn't feel very good, like last night, we had a giant shootout at long range with a lot of cover ducking and so on. The enemies had seeker rifles with a range of 120 feet, but many were shooting outside of their range increment. I was playing an elf solarian at level 3, I anticipated some issues with getting close so I went for max speed, I had a 40 foot movespeed + 10 circumstance from SR, so I could move 100 feet with two actions, and 140 if I used all three actions.
Unfortunately, the enemies were *just* outside of that, and obviously they saw me charging across the battlefield to get into position, so they naturally decided to all focus fire me. I went down, and it took forever for my allies to do anything about that because of how far away I was.
The issue is, at such long ranges, you have basically nothing you can do as a solarian. Youre going to be shooting with solar shot at a gigantic increment penalty (though now I look at it, it seems you can't attack with it with increment penalty), just taking cover is boring, and your shield has 1 hardness.
I guess you could carry around a long rifle precisely for this... but thats kinda boring too, right? Like your whole thing is baked into this big melee weapon you can manifest but for 1-3 turns of combat you won't be able to use it.
Then if I did get close enough to those enemies, they were spread out enough that it'd take many actions to even begin to think to do anything to them.

I really like, conceptually, some of the later feats that help with this , like Feat 8 Flicker Strike, Feat 8 Momentum, Feat 12 Covering Flare, Feat 12 Wormhole, Feat 18 Homing Mote. However, they come online *so late*, it feels like almost every battle is going to be a grueling unfun affair with this class in such a ranged system. It also feels like feats like these are *mandatory picks* so you can't do any other build.
I feel like some feats/subclass specific abilities that are early that let you pop around many parts of the battlefield would be useful and fun. Something like Reversing Charge from Chronoskimmer in PF2e, but early.

As for the rest of the playtest, the Operative, Mystic, and Witchwarper looked super fun for those players and I'm curious to try them out myself
