Li Shenron said:If you want the same aid from an NPC, you have to "give him" full XP as a normal PC. A cohort gets only half XP, therefore you are acually gaining (or saving) XP because your friend took Leadership, and now the party can afford more or harder or easier encounters.
And if I want to (if alignment permits) kill the poor sot for his stuff, a regular NPC is just that -- yet anotehr regular NPC.
However, I'd tick off a fellow player if I went around doing the slice-anddie to his cohort.
...
There's also the fact that I would have LESS say in wether or not the cohort can tag along, than I would about a generic NPC.
And again: an NPC 2-4 levels below the average party level is not making a significant contribution to encounters. If anything, he's a greater drain on extant resources.
Woe unto the party when their cleric gets a "meatshield" fighter-type cohort; you know where most of THAT cleric's healing is going ...
... straight into their own (lower AC, lower HP) cohort.
