Here are some things that spring to mind, which could be useful for new players I think:
You've already touched upon this subject, so I don't know if you had already planned to include the following or not, but I think it would be good to go through things like the need to use some particular skill(s) X number of times per day for Y days (the Y changing depending on at which level (1, 10, 20....) the deed becomes available) in order to acquire the class trait connected to it. And also include mention that accelerators can be used, not only to double the accrual rate, but also to bypass the daily limit (X) - something that's definitely not immediately obvious to most players, least of all new ones.
Another thing that is not apparent at all - in fact it can be very problematic to understand at first, since you're given NO help/tutorial/advice or even clue from the game at all on the subject - is what Stable Points are and how Stable-Masters work. Specifically, that you have to first actively click on any Stable-Master you find in order to 'discover' that particular location, in order for it to be possible to travel TO that location later, and also the somewhat subtle difference in icons between a 'discovered' and 'undiscovered' stable-point. It's very easy to miss these and just move away from the area if you don't happen to need to go somewhere else at the time, so that you might very well find yourself forced to manually ride there later, or even worse; run.
Add to this the confusion that some stable-points 'activated' by default so that you can always travel to that location without needing to discover it first (MD, TH, Celondim, West Bree), whilst most others are not. This is particularly strange in Bree-town, where West Bree is always available, but South Bree is NOT; it has to be manually discovered first...
I have no doubt you have already planned to include this somewhere, but I mention it anyway just in case. Since it appears that alot of people have no idea of how to operate within a group environment - even at higher levels! - since many just level solo or "with friend(s)" through the whole game, I think it would be very beneficial (to ALL, really, not just new players
) to really go through some of the basic concepts involved in grouping in this game.
- Settings. Aed already mentioned mentioning of 'Vitals of Selection's Target' (and how it works), but also the many other Combat and group settings in Options; Raid Assist Target - what it is/means, the window, how to enable/move/use it (and how to follow it!!! ).
- Roles. 'Tank', 'Healer', 'DPS', 'CC' - what each one is and what they do (and don't do); what is expected and what you should/should not do in the particular role you happen to find yourself in as well.
- Threat. Learn what 'threat' is - at least a basic understanding of the concept - and how to manage it! At a bare minimum knowledge such as "Who has aggro?" and "Don't pull aggro - of anything! - if you're not a 'tank'". Personally, I would also add valuable information about what to do (and more importantly: what NOT to do!!!) if they do happen to pull aggro. This is knowledge that sadly seems to be completely foreign to a lot of players even at lvl85 these days - and it's only getting worse, every day.
- CJs. (I can hear Aed cheering even from here, hehe) What they are, how to trigger them, when to use them (and when not to), what each colour does by itself, how to build them into longer onces (straights, flushes and 'around the wheel' in either direction) and some common/good examples.
- LFF. How and where to advertise, to form a group or to join one. Basic understanding of what (roles) are needed in general, for different group sizes.
- Maybe something else as well...
I can honestly say that I had NO clue whatsoever about most of these things myself, when I first leveled up - even well into Moria! Haha
These are just some things that came to mind for now. I might think of some more later.
For my own part, the thing that confused ME the most (by far) was trying to grasp the LI system - tiers, ranks, major/minor legacies and the differences between them, and learning how to read those damn 'rune' symbols on the items.
I found that, while the game does give a 'tutorial' on the whole concept, it is woefully lacking. Hopefully you'll give a broader, deeper and better structured clarification on the subject.
It might also be a good idea to include some knowledge that only comes with a lot of experience - thus answering some FAQs, as it were - such as:
- When deconning a LI, it is wiser to extract a MINOR legacy that you want (over choosing a major one, in case it has both), since it is far more difficult (and a real gamble) trying to find a minor when you need it than it is a major (which shows up on ID).
- When to deconstruct a LI depending on purpose (legacy extraction, relics, ...).
- To always try and keep all LI slots filled unless you need to have one (or more) slots free at the time, for maximum per-unit IXP gain from e.g. quest rewards and such.
