Heretics faction for Cleric quests in Paineel

[DBStrong]

For issues relating to survival, I have not bothered to conspire to break in to the city just yet, but I'm wanting to know so that I might go ahead and try it:
Q: Would a Human Cleric of Innoruuk start out as KoS to the Paineel Cleric GM?

My cleric is KoS to the skele guards in Paineel newbie area. Can it be assumed then, that the rest of the city proper would /con the same? If that is the case, Q: what is the path others have taken to raise faction to at least dubious so they can do the repeatable faction quests such as bat fur & beetle legs, or bat wings & snake fangs.?

Not that the faction hit(s) would be a deterrent, but being somewhat of a lowbie, killing Erudin guards isn't quite an option just yet, otherwise I would happily go that route.

Doing some homework, and poking around in Toxx, there is a mob to kill that raises Heretics, at the expense of most all Erud factions, and I have been killing this mob as often as I can, but Q: do other more expedient options exist, as opposed to this painfully slow grind of killing this L6-7'ish mob every 12 minutes.

(((Also, I know once Warrens is 'in' all this will be moot, but even without knowing the timing of that release, it is far enough out to not be a viable option. Thanks to those forum folk being so wise as to suggest this solution.)))

Thanks in advance for any and all insight on the topic. Still learning, and I appreciate your genuine input and thoughtful replies.
