You can only get AN from event driven content though. IS is pretty slow from xp, with few exceptions to enhance it, otherwise it is primarily earned from event driven content as well. Also, both IS/AN are really only reasonably obtainable once you reach a certain point in the game (level, reputation, etc)--barring you sneaking in and running campaign ops in the past I guess, but that will be restricted to your 7 credits per conquest tally.

Not saying I'm against them making CP obtainable via event driven content as well. Just stating that it normally would be easily obtainable. CP is earned from day one, at level 1--and has a fairly simple mechanic for increasing that reward by 50% as well. The problem is, people aren't earning XP like they used to, and are thus not earnign CP like they used to either. "Old-school" leveling would easily grant you anywhere from 25k-35k CP before you got to TAU areas (if not more) on just one job--simply from joining normal XP parties along the way. People simply aren't taking this route these days with all the other options--FOV/GOV/Abyssea, etc. Instead, they are getting massive chunks of XP and essentially skipping levels, and missing out on the CP they would otherwise have gotten simply from killing mobs for xp and not as a bonus reward for completing pages and such.

Until they do something about it, players need to be mindful of just how to optimize their CP gain--that means keeping Signet up and fighting in Conquest areas not under your nation's control, geting as much raw xp/kill as they can along the way (the amount before xp band is applied).
