Eschew materials can be good in pnp, you dont have always the opportunity to buy new spell components, and havent the carrying capacity like in ddo.
Just fill up every component you are using to 990-1000 once every 2 days and you will be fine. I started my arcane casters with 8 base str, and it works fine, just use the right str item for your level.
Every char has to check consumables, i expect everyone to have remove curse potions, lesser restoration potions and other means of healing, at least after level 4-5.
