As for collecting keys. I have virtually stopped running the grave yard. I find that one of my toons. A 1st lifer Dark Hunter has the d***est luck in quests in getting keys. So, when I run out of keys I hop on that toon and run quests.
As for new people coming into the game. The guild that the wife and i belong to have two brand new players. As in having started in the last couple of months new. The learning curve for this game is steep. I had forgotten just how steep until they started to ask questions about builds and what to do in a quest. One of them, the other night pops into the chat room saying he started a to run a wizard. !st life wizard, new player.... I wish I were just that new and naïve to think the game would be that forgiving of a new player running a 1st life wizard, solo. I guess I am somewhat of a curmudgeon these days.
I do not play casters myself,(yeah, I am going to have to at some point to get completionist) but I did have some gear and extra plat to at least give him a fighting chance. Some other decided to join him on Korthos with low level toons. His question, by the way, was how do you get your spells to work. The game should at the very least show that to a new player running the grotto. But that is just me and my own opinion.
