No, I believe your right about the shared and piggyzone...hell, I'd even go so far as say, I agree with the afk macroing...in open zones.
They are not going to ban someone who quitely grinds away XP in FH.
I could understand if...they were doing HoH, or that little place in WoS. But unless your doing something COMPLETELY jack off-ish in Nedarias Landing, they will leave you alone.
Your not interferring with anyone, hindering others gameplay etc. Macroing, both in FH and other things like tradeskills, is how WE ENJOY playing Everquest.
If we are not KS'ing someone, taking their loot, camps, or general XP, OR for that matter inhibiting someone from enjoying their style of gameplay....then leave us to enjoy ours.
Personally, I NEVER use MQ2 to cheat someone out of anything, or gank a mob on them, or anything like that. I use it because unlike some people, I cannot play EQ 24/7 that is required to be able to keep up with my high lvl friends, just so I can play with them. MQ2 has been a god send, it allows me to do work around the house, exercise, spend time with wifey, play with dog, read, enjoy other hobbies, and still be able to spend some time a couple times a week enjoying EQ at the level I like to.
Bottom line is, if your not duping items, artificially inflating the ingame economics, or ruining someone else gameplay, then the GM's will leave you alone. If they don't, that's really shitty, and you don't wanna be playing a game run by assholes like that anyways.
Besides.....who the heck could you possibly be hurting in FH or Vxed? Their instanced zones for one, and are attached to "Dead" zones with little to no traffic.
