In response to the AD parts:
also don't forget if the damage output from the calculation results in a higher amount than the damage cap (if there is one: example - some servers have a 400k damage cap) then AD will miss all the time. Usually it's not just a matter of flee but instead increasing the amount of int you have. At least that's how it's played out from what I've seen.
As far as getting AD/Homunculus, that's dependant on your build. It's possible in a full kamikaze type battle build to have AD, Homun, and Potion pitches, but you lose out in other areas. It's possible, but the likely hood of people using such builds is completely up to the players

most alchemists think it's ungodly not to have fp or at least some sort of chemical protection... So really it's just how you want to play your alchemist :p
