First set to 80 took "7 days 23 hours 28 minutes", a few hours less since I've been doing the daily solo shard run {which can be done in a group...just can't auto-follow in shade form}.

I swapped out the mystic and conjuror for a defiler and warlock. Because my RAF is not optimal {C&D >A, E&F>B} I mentored A>C and everyone else to D. My XP bonuses look like this

Toon C
"You are earning 5% bonus XP due to being mentored.
You are earning 10% bonus XP due to being mentored by a friend.
You are earning a 200% adventure XP bonus for helping a friend.
You are earning a 10% adventure XP bonus for having max level characters. {1 80 from the old team}"

You are earning a 200% adventure XP bonus for helping a friend.
You are earning a 10% adventure XP bonus for having max level characters. {1 80 from the old team}"

All other toons

You are earning a 200% adventure XP bonus for helping a friend.
You are earning a 10% adventure XP bonus for having max level characters. {this is on the current 80 toons}"

1-71. 1d 13 hours played.

We just went straight through dungeons, so our AA on the new toons sucks, but we aren't sweating it. They're at 51 AA, but once we hit level 69, we went to Kunark to start them through the quests there. They should pick up a bit of AA through playing catchup on all the quests our main team already did and we'll see where they're at once they actually hit 80. We don't intend to do much for dungeons until we start working on thier fabled weapons. On the other hand, the 80s we mentored all got 15-20 AAs in the process of leveling up the newbies, from new dungeons and converted Adventure XP.

Edit - Yes, EQ2 is a TOTALLY different game than it was on release. We played at release and hated it. We played again about a year after release and still didn't like it. We came back maybe a year later and played for about a year or so. Now we're back again and really enjoying ourselves.
