As I don't care to get into an argument of rehashed statements, as you have made it clear you will not back your claims with anything more than your forum name, I will merely address this point: I would not believe that ANYONE who played a caster a lot would say they never use pots truthfully.
BTW, endless mana pots argument is a strawman. I have, in three years of playing, only met a couple people with endless mana pots...and even that doesn't make up for lack of experienced play....and not being a FvS had more to do with not wanting to heal ungrateful idiots than not wanting to drink pots (I've drunk more pots since going arcane, as I try to get solo achievements now).
