best linking set up

Right now i have:

Ac#1 (invite Ac#2 and linked)
Ac#2 (invite and linked to Ac#3)
Ac#3

I am getting two new accounts and wondering if the best policy would be to link them both to ac#2 and then just have them always run with a toon on ac#2 for the x3 experience and multiple gift levels on ac#2. On my set up now i had a high level on ac#1 running two new alts on ac#2 and ac#3 and both the accounts were getting x3 experience on quests but only one was getting the experience boost on mobs. What was that about? Doesn't make any sense. 2 and 3 are linked so i thought they should be getting the same benefit with 1 regardless of who 1 was.

since account 1 and two are linked.. they have to be withing the same level.. of each other.. if your boosting 2 and 3 wtih your level 70 on account 1 then 2 wont get the xp from mobs..

read. before you do. there's ALOT of info already in this forums.

if you start 3 new toons.. all level 1 on all three accounts.. then yes.. all 3 will get all the bonus of xp.
