One of my pet peeves with the DDO game is that so much information is only available via third parties such as the ddowiki. I don't expect DDO to provide any kind of spoilers for dungeon runs like you can find on the wiki. I do expect them to provide the basic information required to allow a player to make a well informed choice about how to use features such as Epic Destinies, Twists of Fate, and Reincarnation on their site, and kept updated.
When I recently hit L20 I had to scrounge around for information on Epic Destinies. I was a VIP player, why couldn't I select an Epic Destiny? The best information I could find on the DDO site was buried in the sales information for the expansion packs. And it was vague and clearly out of date, since it referred to the level cap as being 25. And since it included obviously out of date information I had to suspect that any of the other information it gave might be also either incorrect or out of date.
I had to submit a ticket to get the information I needed to make an informed choice, and that necessity probably wastes far more DDO employee time if repeated over and over across the player base than simply making the information available on their site and then maintaining it.
And then I had to post on these forums to figure out the confusing mish-mash of information concerning Epic Destinies and Twists of Fate. Again, this information should be provided by DDO in a clear and unambiguous manner. On their site, and not relying upon some third party to provide it for them and keep it updated. For me, the information on ddowiki was not enough to clear up how EDs and Twists inter-operated. A set of FAQ Q&As would probably handle the issue nicely for most people.
Ok, rant over.
Never throw away nothin'

Ok, there are a few exceptions, like useless dungeon quest items which don't auto-drop when you exit. But it's a good general rule.
I'm right there with you! I now keep a file on all my characters, with entries that look like this:
5,3/6,7,6,2/5.5,2,6,1,6/3.5,2.5/3
If you look at this while looking at the character appearance screen, you'll see how it will let you get as close as possible to your old appearance. Unfortunately for me, I didn't do this until after I had played my main for quite a while. So I will need to try to capture her appearance before I reincarnate.
Does this (specifically saga status retention) also apply to HRs? And if so, will you retain access to places like GH so you might complete the saga there, HR, and then use the saga EXP reward as a very nice leg up in your leveling?
As in:
1) Finish GH saga;
2) HR;
3) Go to airship, ask navigator to send you to GH even though you are L1;
4) Turn in saga for 46k EXP (plus any bonuses for EXP potions or Voice of the Master, etc.);
5) Profit!
This is quite handy, thanks!
