A Title Much Cooler Than Anything on the Old Site
My answer to your why not would be yes exactly why not get rid of them.
Do having little tarts in a pouch make your character more awesome?
Or was it the rotten eggs and skunk cabbage?
How many cups of water does your component pouch hold?
Simple, component pouches are magical bags of refrigerated holding!
Going with a focus that can be charged up for the costly spells seems an obvious candidate.
We'll be keeping the requirement for components with a cost associated as per raw. Basically the expensive gems are another specific focus needed to cast the spell, one which will be consumed.
