Aurelion Sol's Star Passive on PBE?

I'm not sure if this is URF specific or if this is part of a buff for the coming patch, but Aurelion Sol seems to gain more stars with level.

I saw in a video that he had 4 stars at level 6 and then 5 stars at level 13.

I like this idea, but I actually had a similar idea that I think would be better, while also giving players a little more control and variation in build path.

What if we left his stars at 3 but increased orbit speed with something like attack speed, maybe CDR, or something completely off the wall like MR or something like that? Preferably something that doesn't often come on items that would make him more 'bursty'. This way with the right items he becomes more of a DPS mage instead of a burst or kite mage.

If you decide to scale it on attack speed, this would make items like and good on him.

would technically help as well, but I see it being awkward to try and stack.

I actually think that giving him more power is good right now because he is very weak against cc and close range combat.

Anyways, that is my idea. Let me know if it is any good, or complete trash in your opinion. Also, what do you think of the addition of stars like what I saw on the PBE? Is that a better idea, or is buffing Aurelion Sol's passive even necessary?
