for zones like befallen/permafrost that have ZERO instances.

Except that those two locations indicate that krono value would rapidly rise, whereas the reality of rising krono value indicate a more gradual slope

I dunno about that, more a question of fall off of farming as a function of the population with those ATMs being present. Either way what comes out of Rath greatly dwarf's any other zone for a good long while.
Still it should not happen in the pass.

The difference is, RM giants requires active farming, whilst HHP just requires u leaving your toon within proximity agro range, with a pet summoned, because the grey con mobs agro you upon spawn, even if you're level 65. This means, if you're going to log off, you might as well just afk at the orc camp with a pet out, because you'll be earning platinum every time a mob spawns in range to agro you, due to your pet soloing it once it auto-agroes you.
