What drives a poor reputation for the Rogue class?

[Witty Username]

To pivot a little,
I feel like assassin could be better at making poisosns, envenom weapons is a thing but that is pretty limited and doesn't really capture making deadly concoctions.

This may be me still being frustrated that according to Xanathar's making poisons with a poisoner's kit isn't a thing.
<Grumbling in general frustration with all forms of crafting in 5e> give me more stuff like herbalism kit being able to make healing potions.

Back to infiltration expertise, I do think the less interesting ability was kept in the playtest, I think it could be expanded to all charisma checks instead of just deception.
