Edit
Sorry if my experiences on these TEs is not fit for the forum, when I had posted I has clicked it from the front page, I didn't realize I was posting in a Beastmaster forum section, never the less with dismiss you should be able to shake any aggro from mobs that do not have pets in the cities. Again take caution with the ones that I had mentioned that could potentially end your farm fairly quickly.

TE1- Gonna probably get aggro here from the PLD RDM guarding it, if you're unlucky the bottom will aggro and cause you some issues, I usually go in with 3 and this has yet to cause any issues that couldn't be handled, if we aggro the bottom, the person who aggro's runs to the enterance of dynamis and just dies after the TE is dead.
TE2 - Same as above, but a little easier to work with, pull the statue and huddle in the corner, you'll avoid aggro at the bottom of the stairs and if you do aggro the PLD or RDM it's not that bad.
TE3 - Very easy pull just have patience and wait for the mobs to move.
TE4 - A tricky TE that can be either a very easy pull down into the bottom of the crafting guild or on either far end of the high rise outside, you can aggro the mobs at the bottom if you are not careful if you choose to fight the statue outside at either end of the high rise.
TE5 - Very easy, wait for the statue to be in a safe position can pull in the middle corridor or down near the entrance where you come in from the back alley, alternatively it can spawn near the second entrance closest to the leather crafting guild.
Bastok -
TE1 - Very simple, just kill
TE2 - Very simple, you can aggro some of the mobs on the ramp if it's in a bad position, remember they aggro sound so pulling may be a bit trickey.
TE3 - Usually a sacrifice kill, hopfully your WHM is /BLM or the person that threw themselves at it has full twilight.
TE4 - The only issue here is Cannonball he's very inaccurate and is pretty pathetic to kill.
TE5 - Same as TE3, there is a possibility that you can kill it without aggroing the entire world, but it's very slim.
Windurst -
TE1 - Clear out the little circle area before engaging.
TE2&3 - Just kill
TE4 - I suggest having a THF sac pull all the mobs around leaving you with a very easy kill, other wise you're going to have a difficult time juggling 2 Avatars, 2 Yagudo and a very high risk of aggroing the mobs right above the TE.
TE5 - Clear the bridge and when the best oppertunity to pull the statue is available to you, go for it, I've had full clean pulls on this, and I've also aggro'd every single mob in the small area, it's about a 75/25 chance that you will aggro everything, if you do best to let the person who pulled it die after the TE is dead.
Beaucidine -
TE1 - Theres some risk that you'll aggro a good number of goblins but they go down fairly easily.
TE2 - Only issue is not aggroing the VT-T Fomors, they take forever to kill!
TE3,TE4 - Pretty simple TEs to kill, they don't have a whole lot guarding them infact TE4 is left completly wide open
TE5 - it spawns in funny locations that could leave you with a BRD or a DRG whaling on you while you kill the TE, nothing to threatening.
Xarcabard -
They're all easy and left unguarded, probably why it's the most popular farm for Solo / Duos
Buburimu - Valkurm - Qufim - Tavnazia
You're just going to have to time your pulls accordingly, as for the 5th TE that moves around the zone, it helps to split the locations between two people if you're going in duo, wide scan also helps if one of you are BST and should probably take the more spread out area where the 5th TEs are.
