Sorry for using your post as my quotes Kailana, This is not meant to be defensive or offensive in any manner. I agree with most of what you say, but for different reasons.
The dunes and qufim are hella popular exp grounds right now, so what you're doing will be noticed, and you know someone will call a GM about it, assuming they don't notice on their own.
All zones are camped by SOME one. Personally I bring my static parties to 'alternate' camps all the time. Beastmasters and BLM's are a prime example of people who will be in these alternate zones you seek.
I would not recommend primary camping zones like the dunes for the reason of respect vs the fear of GM. Qufim is debatable. Its not a primary camping zone, more of a nice alternate.
Are there any zones that aren't frequently exp'd in that would be good for this?
I've been thinking of prime zones for this all day/night. Beastman strongholds are the best thing i can think of for a couple reasons. The biggest being that Beastman link and they will aggro /heal so your puller can get them without putting damage. There is also high concentrations of mobs to link up. Ghelsba, Giddeus, Davoi to name a few providing they fit in your level range.
Please be discreet where you do this. If you end up clearing the zone a few times, then another smn pt moves in and does the same thing, etc etc, then yeah, SE are gonna notice.
Personally I don't care if SE notices. This functionality has been around since the summoners have been.
This is not a 'Bug', this is not an 'Exploit', therefor theres no need to try to hide it from SE. This is simple game function's that were meant to work as they are. Granted its much easier to do now with level synch, but its nothing new. Just one of us saw a way to take advantage of our 2 hour ability in a way that no one else had thought of.
Its been said by others to which I agree and reaffirm that this is not 'Ground Breaking'. By that I mean people are not going to stop leveling in partys because a summoner can get them a huge bang of xp in a short amount of time. Its just a new fun way for summoners to level without wanting to relying on the 'traditional' methods. No different than BLM burn parties really. Except we take our burn party and do all the mobs at once.
Again these are just my opinions. I dislike the argument of fear of GM's, I believe if you treat everyone politely and you follow the golden rule then you'll have no issues that a /blist can't fix.
