What drives a poor reputation for the Rogue class?

So the quick assement,
Say stealth for an assassin. By the tier 4 range they will get a +17 to stealth and reliable talent so auto success if DC is 27 or less.
These are good numbers but it does run into an issue that in optimized groups use pass without trace alot which gets the floor to +10, something like a monk or ranger will be rocking a + 21 due to that, or a respectable +15. It creates a weird paradox of optimized stealth groups are discouraged from actually investing in stealth because beyond your spell buddy.

This is part of the reason why awhile back, I asked about allowing the rogue to share its stealth check as a addition to Thieves cant. Ultimately being good at stealth individually is just not useful in upper end groups.
