Other classes get cooler and more powerful options as they level. The soldier and operative get to shoot three times, the operative opens up an entire buffet of new powerful options from full on invisibility to having bat shark repellent if they need it, the mystic starts getting higher level spells...
But the envoy is still capped at level 8 abilities. From 8 all the way till 20.
Even worse, by definition after your 2nd or third pick you're not only stagnating in your options, you're picking less and less useful more and more situational options. The envoy doesn't have the action economy to pick up more tricks: they just can't make use of them in a single round. Its barely growing out and it's, if anything, growing down not up.
With the com as a chance to change this having passed it doesn't seem like there's any desire/no one sees a need to do fix this. This is a pretty big problem when one of starfinders aparent design goals was NOT to break/devolve into rocket tag at double digit levels.
