You guys are trying to pass the blame to the veterans. I say stop that. As a player that has mostly played consistently since 2.0 launch I can say that if the new players are so desperate to learn the new content then find other new players willing to do it and don't try to leech off the veterans with higher gear to drag you through it if its so important to your "experience".
If you feel the way they do things is not in line with your expectations find a different way.
You forget they are not here to service you and your desires. They are players who have responsibilities outside of the game and don't have time to do content the slow way or retread the old ground they have walked over thousands of times because you demanded it/needed it. They have goals to make themselves better in other ways in the game that take time. The reason most content is optional is because SE realized this flaw in the game and that players did not want to do the same content 10000 times over to help bring up the bottom line of the player base.
If you truly can not find help I do feel for you, i've been there but that just means you need to find players who are more friendly and wont treat you like a number in their FC or LS (if said LS is based on this theme).
As an MMO you are late to the party and therefore do this the way the vets do them or spends countless hours trying to do things the "pure" way. Altho that's a lie too because unless you do content at minimum ilvl the dungeons/ex content are still much easier now due to higher gear levels then they were when they first came out.
Every MMO has worked like this and players should do some research and ask around about why its like this rather then be against it. It's progress. It happens in every MMO where old content is phased out making way for content that is on par with the rewards the players of higher level require to further better themselves.
I am a mentor. I may come off as a bit aggressive sometimes, I know this, but when I see a player in a dungeon or primal using a rotation that severely limits their dps ouput I try to give them advice. Guess what that advice is met with? I either get complete silence back with no change to their rotation or feedback about it or I get told to mind my own business for trying to make a player better then they already are.
I try to help still but to a much less degree because no matter how you word something to another player about what they could do to get more out of their role you will only ever sound like a condescending twat to them when you had no ill intentions in the first place. They always see what you said as "oh so hes saying I suck".
In the end its up to the individual to get better, to want to be better. Tooltips tell you everything you need to know about certain skills and traits yet most ignore them. It is due to their own ignorance that they are falling behind and it has nothing to do with the game itself.
A player mentioned titan and how they could not teach someone basic skills. That is true. Some things in this game you just cant teach like reaction time, common sense. I can only watch as someone can get hit by the same mechanic so many times before I just give up and rather not waste my time when I could be leveling another job or crafting an expensive gear piece to sell or actually helping a player that wants to be better rather then think the game revolves around them.
Thats the biggest issue with the new players of the MMO genre. They don't see themselves as a burden to other players. They think they are the king of the crop and the game is ment to serve them when in reality they should have the opposite mindset and see themselves as a player who may burden others. All the long lasting/High skill players have this trait when traversing new content or walking down paths not taken yet. I rarely see anyone apologies for messing something up or taking responsibility for their actions. I still do cause when I mess up im taking time away from other players and I am aware of what i just did unlike most of the playerbase.
I rarely see it but the minute I see someone feel remorseful about what they just did and apologies for their actions, maybe even explaining that they are new and are getting used to it so forgive them if they mess up further, I will carry that person on my tiny lalafellin shoulders and do whatever they want cause I can tell they have potential by the way they felt remorse. (Obviously when I have free time to spare.)
TLDR: Your late, if you don't like the way things are handled then leave. The new players are more to blame then the vets from how I see it with their lack of remorse and self awareness. If someone wants to be better they will be, its not something you can fully teach someone.
